Station assembly QA /comb - i
Comb arrived: 9 May Doublet layer arrived: 15
May
Length of the scintillating fibre is about 40cm, bit short to play with comb
Need to shift doublet layer on vacuum chuck
For bundling of the fibre, better to cut the fibre to the same length
For the production version, the length of the fibre > 50 cm, will be OK
40cm

Station Assembly QA - ii
Comb holder made;16 May
Vacuum tube connector
Comb position adjustable
Scintillating fibres tangle up to comb’s slit and teeth=> Needs cover on top of the comb

Vacuum chuck
Vacuum pump switch
Suction on/off switch
Tube attached to vacuum chuck
Vacuum pump is quite noisy;better to move outside of the room to make a worker friendly environment

Straightness check - ii
Align the vacuum chuck with alignment pinuntil the fibres on the CRT and the crosshairs on the CRT match
Then scan across the fibreto check deviation from straightness
Stage controller boot sequence;1. Double click
D:/Microscan/Microscan.ht2. Open MicroScan.txt on desktop3. Copy texts to hyper terminal4. Type “man()” then press return;
a text “UNDER MANUAL CONTROL” should appear onLCD of SPECTROLAB MICROSCAN

Todo
Tools and parts scattered around in the room;need to tidy the room for efficient work
PC for stage controller too slow;Windows XP running on Pentium 200MHz with 128MB memory; ridiculous10 minutes to boot; 10 minutes to shut down
Finish straightness check
Try bundling with comb
