1. Takashi Matsushita t.matsushita@imperial.ac.uk Imperial College T. Matsushita 1 Quality Assurance 16/05/06

2. T. Matsushita 2 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

3. T. Matsushita 3 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

4. T. Matsushita 4 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

5. T. Matsushita 5 Microscope with CCD CCD Light controller Stage controller Video text overlay switch CRT

6. T. Matsushita 6 Straightness check - i Unmount vacuum chuck holder; Be careful to this pin Put holder on stage Fix the holder x y

7. T. Matsushita 7 Straightness check - ii Align the vacuum chuck with alignment pin until the fibres on the CRT and the cross hairs on the CRT match Then scan across the fibre to check deviation from straightness Stage controller boot sequence; 1. Double click D:/Microscan/Microscan.ht 2. Open MicroScan.txt on desktop 3. Copy texts to hyper terminal 4. Type “man()” then press return; a text “UNDER MANUAL CONTROL” should appear on LCD of SPECTROLAB MICROSCAN

8. T. Matsushita 8 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; ridiculous 10 minutes to boot; 10 minutes to shut down Finish straightness check Try bundling with comb
