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, 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/comb - ii Comb support made; 16 May Vacuum tube connector Comb position adjustable Scintillating fibres tangle up to comb’s slit and teeth => Needs cover on the comb

4. T. Matsushita 4 Vacuum chuck Vacuum pump switch Suction on/off switch Tube attached to vacuum chuck It works! 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 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 It works!

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 Put vacuum chuck on the holder Align the vacuum chuck with alignment pin until the fibres on the CRT and the cross hairs on the CRT match => I found this is very difficult, could not make it Tried to read coordinates shown on the CRT. But cross hairs cover about 6mm and the resolution is not good… By the way, 0.5mm shift over 300mm is 1.7mm radian. Do we really have 120 degrees shifted planes? Probably we need to use station acceptance rig to check straightness of fibres as well as relative orientation of each plane. Any idea? 1mm

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, to be replaced; Windows XP running on Pentium 200MHz with 128MB memory; ridiculous… 15 minutes to boot; 15 minutes to shut down… Try bundling with comb Prepare LED scanning system Prepare connectorisation bridge
