MedOptics CCD @ G3 - Check List
=================================
I. line-up
A close main shutter
B ccdoff
C mv del 0 gam 0
D move CCD back
E cover CCD
F remove lead mask on Be window
G mount ion chamber and slit
H horizontal slit gap should be 0.5 mm, vertical gap 2 mm
I shopen
J line up in the direct beam
a mv mu 0 zeta 0 chamy -1 att 3
b dscan mu -1 1 20 1; mv mu CEN; set mu 0
c dscan del -1 1 20 1; mv del CEN; set del 0
d mv chamy 0; dscan chamy -1 1 20 1; mv chamy CEN; set chamy 0
e dscan zeta -1 1 20 1; mv zeta CEN; set zeta 0
K line up incident angle with the reflected beam
a mv mu 0.3 zeta -0.15
b dscan zeta -.2 .2 20 1; mv zeta CEN; set zeta 0.15; laser
c dscan chamy -1 1 20 1; mv chamy PEAK; laser
d put print-outs of final line-up scans in the log
(J and K correspong to scan macros rock and refl from dmacros.mac)
II. CCD measurements
A ccdon
B remove ion chamber and slit
C tape lead mask onto Be window using the marks on the window edge
D remove CCD cover
E move CCD close to Be window using marks on the dove tail
F make sure all six plastic screws of the CCD holder are hand-tight
G mv del 18.5 gam 2 att 0
H take some typical dark images: dark 0.1;dark 1;dark 5;dark 10
I take a test images to check set-up: take 0.1; take 1; take 10
J take images to record scattering background: take 1;take 5;take 10
K start growth: tseries 100 10
L monitor CCD intensity and reduce exposure if needed
III. post-mortem CCD scans
