Rectifier converts 220 V AC to 380 V DC.
Rectifier is in non hazard area (control room). MARATON Power Supply
(PS) converts 380 V DC to 8 V DC. PS has 6 channels, 4-8 V DC (rated
2 x 150 A, 2 x 100 A, 2 x 50 A). It is modification for EMU with air
cooling. MARATON is in hazard area near the detector. MARATON supplies
a peripheral crate (4.5 V DC and 6.5 V DC) and a CSC (analog channel of
7 V DC and digital channel of 6 V DC)
Who will assemble MARATONs (put in their places on the disks)?

possible. Grounding bar is still waiting to add to
the junction box. Plan is to make one copper prototype and to
assemble it to the existing box. Dick took the drawing of ground bar
to investigate how to make it at U. of W. Also Sergei wants to talk
with Dan about tin plated copper bar.

distribute power and to organize CAN chain for one side (near or far,
+Z or -Z) of 3 disks. The chains are organized by Ethernet Cat5e
shielded cables.
