Line Broadening
1) Collect 1st spectrum without compressor running
W202
Test Input: 2 Lines OK
1500V, wait 30s, clear Data
If required change V to accommodate peaks
Set windows on escape peak excluding noise and on 14.4K
Lines visible = peaks set
Send windows, Δ = sent
Exit
W302
2 mm/s
Monitor V transducer; err ≤ 40 mV PP
Count rate ≈800c/mCi = OK
Channel 1 Plot, see spectrum, wait 30minutes
Save data (in default w302_1.txt), folder should be on desktop
Open w302_1.txt, put remarks at bottom, save as yymmdd…
2) Collect data with compressor running + temperature set ambient
SAME
3) Run WMOSS to check Line Broadening
(Check Reference “A” at Bottom of this text 1st)
