16 February, 2019

2. Sample Environment Reference Suite
Sample Environment Reference Suite based on instrument needs. Timelines determined by instrument construction schedule.
NSS construction budget covers the needs of the first 8 instruments #1-#8. Additional budget provision for instruments #9-#16 in (pre-) ops 5yOPS19-23
Most Sample Env. Equipment is within SSS budget but some instrument specific equipment remains part of instrument construction.
Execution responsible involves (potential) expert team as agreed.
Budget leverage: refurbished equipment; collaborative projects; grants.

10. Questions for STAP Day 1 priorities for sample environment?
Motion axes needed
Magnet for spectroscopy – endorsement by STAP helpful
Magnet for spectroscopy – advice on trade-offs:
Field (min acceptable)
Angle (vertical & horizontal). Multiple positions acceptable?
Max amount of material in beam.
Internal guides, collimation?
Experience with SE/instrument integration – major things to plan for (e.g. force testing, vacuum testing, adequate utilities, chopper interaction).
