> Stack has been changed in configuration from a 6 DSSD stack to 8 DSSD stack. > What was detectors 1-6 are now 3-8 with 2 new detectors added to the front. > > The stack order is now: > DSSD 1 3058-25 Top > DSSD 2 3058-2 > DSSD 3 3058-4 > DSSD 4 3058-3 > DSSD 5 2998-23 > DSSD 6 3058-5 > DSSD 7 3058-6 > DSSD 8 3058-7 Bottom > > To handle the new detectors an additional 4 FEE modules 8 FEE64 were installed in the system with MAC addresses: > FEE 25 - 2B 09 E7 > FEE 26 - 2B 22 55 > FEE 27 - 2A F6 D4 > FEE 28 - 2A ED 8F > FEE 29 - 2A D0 1A > FEE 30 - 2B 33 0C > FEE 31 - 2A B6 45 > FEE 32 - 2A B2 B2 > > FEE Mapping is now: > FEE Number > DSSD A B C D > 1 25 28 30 31 > 2 26 27 29 32 > 3 1 20 22 23 > 4 2 19 21 24 > 5 9 12 14 15 > 6 10 11 13 16 > 7 17 4 6 7 > 8 18 3 5 8 > > All 4 new p side cables were made using 33" ribbon cables > The n side cables for detector 2 were made using 37" cables > The n side cables for detector 1 were made using 39" ribbon cables (37" was to short) > > Non-isolated cables related to C connector on DSSD > > The detectors were placed inside the snout with two reference lines for insertion. > The first labelled as June 18 6 stack will place the centre of the detector stack (Between detectors 5 and > 6) in the centre of BRIKEN > when inserted up to this line. > > Distance from edge of BRIKEN to centre is 37.5cm > > The second mark is 1cm along from this and is labelled June 18 8 stack. This positions the centre of the > stack (Between detectors 4 and 5), what would be 3 and 4 if only 6 detectors) > in the centre of the BRIKEN array. > > One thing to note is that with 8 detectors getting the snout on is a tight fit and can push down the rods > the detectors are held on. This was previously > a friction fit between the rods and the snout base. The rods had to be pulled out slightly to allow for the > extra length needed for 8 detectors. > To aid in the rods were not slipping grub nuts were moved to the bottom and locked in position. This may > not hold the strain of someone pushing the snout against them so caution > is still advised when putting this on. > > When in the 8 stack configuration DSSD 1 is 4.5cm from the end of the snout. To support more detectors > longer rods would be needed though.
