Our technical problems seem to be solved, and I hope that you will contribute to the list with announcements, opinions, questions, answers, and comments as before. The mailing list runs on a new platform, and you have all recieved the first automatic mail from the new system. I am even more happy to announce Peter Willendrup as the new tecnical responsible of McStas, as of July 1st. Peter replaces Per-Olof AAstrand, who is now a full professor of Theoretical Chemistry in Trondheim, Norway. Peter has a background in experimental physics and computational science, and he is now working full time on McStas. I am convinced that after a short start-up period we will be able to retain the level of McStas user support that we had earlier. Other issues high on the McStas agenda are - Upgrade McStas to version 1.6 and beyond - Release of a component manual - Continuing the code comparison project, - Continuing the construction of "real" sample components More information on these issues will come later. All the best, and many happy simulations Kim ------------------------------ Kim Lefmann Senior Scientist Materials Research Department Risoe National Laboratory Phone: +45 46 77 47 26 Fax: +45 46 77 47 90 From farhi at ill.fr Thu Aug 1 19:11:49 2002 From: farhi at ill.fr (Emmanuel Farhi) Date: Thu, 01 Aug 2002 19:11:49 +0200 Subject: [neutron-mc] All the best for McStas Message-ID: <3D496BD5.3049D669@ill.fr> Dear McStas users and Monte-Carlo neutron simulators, This is just great. You probably noticed the new McStas site, which is efficient, and pretty looking, as well as the resurection of the neutron-mc list (with all archives, and the full list members). I have updated most of the ILL McStas site links to the Risoe site. I would like to join Kim and Peter in saying that we have a lot of plans for the near future of McStas. First of all, we shall continue the work around what we started together last december in Risoe, where the first step towards version 1.6 was done (It's today called 1.5a). Among the items on the to-do list, here are some points we are thinking of: 1. the NeXus format will be looked around, and possibly included in McStas soon 2. new Kernel features (groups, share, extensions, possibility to restart a simulation, intermediate savings... ) will inspire the next release 3. the installation problems that are now encountered on various systems (perl libraries) will be looked at, and we should hopefully come to a solution 4. probably new components (inelastic... ??) I'd like to invite all of you to participate and give a lot of comments/ideas (and possible solutions if you think about some), so that the next release becomes yours, including all that you would like to see inside. Also, if you have components that may be usefull to others, please send them to Peter with a note explaining quickly how it works, and a usage example (reasonable parameter values). Hope you will enjoy what's coming soon !

You are right - originally (1998), a beta version of McStas existed which had windows support. Unfortunately, supporting McStas on windows ended up requiring more work than RIS? had at the time, hence windows was removed from the list of "supported platforms". (At the moment, the supported platform is a unix type operating system, e.g. Linux, Solaris, HP-UX, ...) I have heard a rumour that someone (in Australia?!?) invested time in porting McStas to windows, and a version was actually on the web. Unfortunately, I do not have more precise information on who actually did this work and whether the binaries still exist somewhere... On the other hand, anyone interested in porting McStas to windows is encouraged to do so! You will get all the help we can possibly give you... Hope this answers most questions regarding windows support. Best regards Peter Willendrup -- ------------------------------------- Peter Kjaer Willendrup, Cand.

For example, many users have indicated that the current setup of the McStas tools (e.g. mcrun, mcplot, etc.) is becoming very complicated to install on some platforms. This will be dealt with in the next release, on basis of the result of this survey. Also, we would very much like to know what versions of McStas that the user base is using and on which platforms the software runs. The survey should only take a few minutes to complete, and is available at http://fys-lin-1.risoe.dk/mcstas-survey You can sign your qustionaire or leave it anonymous, as preferred. We hope that you will find the few minutes needed to complete the survey, and thus help us in making McStas a better software. Note: The submission deadline of the survey will be Friday September 21st 2002.

Thanks, that would be great. In the meantime, I have been experimenting a little bit with cygwin (http://www.cygwin.com/), a GNU runtime environment for win32 platforms. It seems that mcstas builds fine using the usual unix approach (./configure;make;make install). I have not had the time to do any real testing, I will report back to the list once I have done this. The GUI tools (mcgui, mcplot etc.) is another matter, since I have not found prebuild versions of PDL and PGPLOT, and compiling from sources does not seem too successful. Anyway, using cygwin is an alternative approach to running mcstas on windows platforms. Regarding the GUI tools, the developer team is aiming at providing an alternative solution to the current Tk/perl/PDL/PGPLOT solution with the next release, since the current setup seems to cause problems on many systems. No deadline has been set so far for the next McStas release, watch the status page http://neutron.risoe.dk/developments/status/ Greetings, Peter Willendrup -- ------------------------------------- Peter Kjaer Willendrup, Cand.

This is my first posting here, so I hope, I am following the rules how to post :) My question concerns the component bender.comp (see testfile and results below): If you make a simple testfile with a Source_flat_lambda, a bender (r=1640 stands for critical lambda 1.8 Ang) and a L_monitor, your results are showing a sharp edge at 10 Ang., which seems to have no physical meening!? So, what is wrong? In an more complex arrangement it seems, that it is possible to move this edge to shorter wavelengths. I am using 1.6-McTas-ILL-Alpha-version, downloaded some months ago.

If we look at the usual formulas for curved guide computation we can write (for the example given) m=2 (coating) H=0.06 [m] (width) Gamma_c = m*0.1 deg/Angs (critical angle) r=1640.0 [m] (radius) Then the critical wavelength is simply (from Mildner and Coppley papers) Lambda_c = 180*sqrt(2*H/r)/2/pi/Gamma_c = 1.22 Angs for m=2 (2.45 for m=1) This means that the transmitted intensity versus the wavelength should vary as Lambda^2 below Lambda_c, tends to be linear after, and then saturates far away. I've been running the 'test.instr' given by Markus with mcstas-1.6-ill-alpha, and new developpment versions. They all give the same result, and it seems reasonable (see mcstas.ps plot from test2lam.dat with 1e6 neutrons) I also attach the files for components Source_flat_lambda and Bender that I used. There may be differences with your library. Please check (specially the source).

Erlangen (Germany) * Version: 1.0 * * Models a curved neutron guide. * * %Description * Models a curved neutron guide.The entrance lies in the X-Y plane, centered * on the Z axis. The neutrons will also leave the bender in the X-Y plane at * the z-value l=r*Win, so you don't have to calculate the real exit coordinates * and you do not need a new arm. The bender is bent to the negative X axis; * it behaves like a parallel guide in the Y axis. * You may either enter the deviation angle 'Win' or the length 'l'. * The bender is shown straight, even if the implemented model is curved. * Thus, you don't have to shift the following component by the curved deviation. * * Example: Bender(w=0.05,h=0.12,r=250,d=0.001,Win=0.04,k=1, * R0a=0.99,Qca=0.021,alphaa=6.07,ma=2,Wa=0.003, * R0i=0.99,Qci=0.021,alphai=6.07,mi=2,Wi=0.003, * R0s=0.99,Qcs=0.021,alphas=6.07,ms=2,Ws=0.003) * * See also Additional note from Philipp Bernhardt. * * * %Parameters * INPUT PARAMETERS: * * w: (m) Width at the bender entry and exit * h: (m) Height at the bender entry and exit * r: (m) Radius of the bender * d: (m) Thickness of the partition, which separates the channels * Win: (rad) Angle of the deflection of the whole bender * k: (1) Number of channels inside the bender * R0a: (1) Low-angle reflectivity at the bender concave side * Qca: (AA-1) Critical scattering vector * alphaa: (AA) Slope of reflectivity * ma: (1) m-value of material * Wa: (AA-1) Width of supermirror cut-off * R0i: (1) Low-angle reflectivity at the bender convex side * Qci: (AA-1) Critical scattering vector * alphai: (AA) Slope of reflectivity * mi: (1) m-value of material * Wi: (AA-1) Width of supermirror cut-off * R0s: (1) Low-angle reflectivity at bender top and bottom side * Qcs: (AA-1) Critical scattering vector * alphas: (AA) Slope of reflectivity * ms: (1) m-value of material * Ws: (AA-1) Width of supermirror cut-off * * Optional parameters: * l: (m) length of bender l=r*Win * * %End *******************************************************************************/ DEFINE COMPONENT Bender DEFINITION PARAMETERS (w,h,r,d=0.001,Win=0.04,k=1,R0a=0.99,Qca=0.021,alphaa=6.07,ma=2,Wa=0.003,R0i=0.99,Qci=0.021,alphai=6.07,mi=2,Wi=0.003,R0s=0.99,Qcs=0.021,alphas=6.07,ms=2,Ws=0.003,l=0) SETTING PARAMETERS () OUTPUT PARAMETERS (bk, mWin) STATE PARAMETERS (x, y, z, vx, vy, vz, t, s1, s2, p) SHARE %{ #ifndef BENDER_DECLARE #define BENDER_DECLARE double bd_sgn(double x) { if (x>=0) return 1.0; else return -1.0; } #endif %} DECLARE %{ double bk, mWin; %} INITIALIZE %{ if (r <0) { fprintf(stderr,"Bender: error: %s: to bend in the other direction\n", NAME_CURRENT_COMP); fprintf(stderr," rotate comp on z-axis by 180 deg.\n"); exit(-1); } if (k*d > w) { fprintf(stderr,"Bender: error: %s has (k*d > w).\n", NAME_CURRENT_COMP); exit(-1); } if (w*h*r*Win*k == 0) { fprintf(stderr,"Bender: error: %s has one of w,h,r,Win,k null.\n", NAME_CURRENT_COMP); exit(-1); } /* width of one channel + thickness d of partition */ mWin = Win; if (l!= 0 && r != 0) mWin = (double)l/(double)r; bk=(w+d)/k; %} TRACE %{ int i,num,numa,numi; double dru,ab,dab,R,Q,arg,arga,argi,Ta,vpl; double einmWin,ausmWin,zykmWin,aeumWin,innmWin,ref,innref,aeuref; double einzei,auszei,zykzei; /* does the neutron hit the bender at the entrance?
