McStas

[kurt.clausen at risoe.dk]

Dear Raphi Schorr

McStas is not a transport code - it is a tool to build a MC simulation
programme for a neutron spectrometer. The spectrometer is described as a
sequential string of components. 
A component can be described analytically, using a ray tracing algoritm,
using a MC description or even using transport code. The code is compact and
meant to be executing fast because it is also ment to be used analysing data
on-line. If you want to describe components with in McStas with transport
code,then you will have to provide the code in C and the cross sections
yourselves.

Yours Kurt

Dear Dr. Clausen,
	I am working on a neutron physics experiment.  I want to simulate
cold neutrons and was told that McStas may be better suited for this than
MCNP.  Does McStas have cross sections for many elements?  I could not
manage to find them on the website.  Thank you for your help.
