The ISIS_Prisma2 Instrument

Simple simulation of PRISMA2 with RITA-style analyser backend.

Identification

• Site: ISIS
• Author: Kristian Nielsen and Mark Hagen
• Origin: ISIS/Risoe
• Date: August 1998.

Description

Demonstrates how the standard components from the component library
may be easily modified for special purposes; in this case to have
the individual analyser blades paint a "color" on the neutrons to
differentiate them in the detector.

Output is in the file "prisma2.tof". The format is ASCII; each
line consists of the time-of-flight in microseconds followed by seven
intensities of neutrons from each individual analyser blade.

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
TT	deg	Take-off angle at the sample position, aka A4	-30
PHA	deg	Analyzer group rotation angle, aka A5	22
PHA1	deg	Analyzer 1 tilt angle	-3
PHA2	deg	Analyzer 2 tilt angle	-2
PHA3	deg	Analyzer 3 tilt angle	-1
PHA4	deg	Analyzer 4 tilt angle	0
PHA5	deg	Analyzer 5 tilt angle	1
PHA6	deg	Analyzer 6 tilt angle	2
PHA7	deg	Analyzer 7 tilt angle	3
TTA	deg	Take-off angle at the analyzer position, aka A6	4
