On the side of the preamplifier, all cables are soldered directly onto the preamp PCB. The length of the cables is about ??cm for each single cable.

Once mounted into a subunit the low- and high-voltage cables from all preamp/photodetector units are grouped and fed to 2 (HV) or 3 (LV) plugs for a fully equipped 16-crystals subunit.

The following table shows information on the plugs/jacks used at the end of the grouped cables as well as on the HV/LV distribution PCB inside the Proto192.

Huber+Suner 640 m (bp) + 947 m (m) + 9620 m (hv) + 1334 m (+hv) + 126 m (s) = 12667 m (maßgeblich abhängig von der Entfernung der HV-Crates)
Flachband 175 (bp) + 229 m (e) + 19 m (s) = 423 m
Filotex 4275 m (bp) + 6647 m (e) + 632 m (s) = 11554 m
LV noch zu bestimmen (abhängig von der Kabelsorte bzw. Kabelaufteilung)

bp = Kabel auf der Backplate
e = Kabel zwischen Backplate und Elektronik
m = Kabel zwischen Backplate und Herausführung zum Magneten
hv = Kabel von der Herausführung zum Magneten bis zu den HV-Crates
+hv = Zusatzkabellänge bei einseitiger HV-Crateposition
s = Kabel für 4 Spare APD-Alveolen

Settings for Nitronic ST215 Coaxial Cable Stripping Machine

U.FL signal cables:
  • Cutting the outer plastic coating:
    • Set the diameter wheel (silver rotating scale) to 1.1 mm
    • Set the cutting length on the upper wheel while watching the red stop piece's position relative to the linear scale. Set it to 7 mm.
    • Set the centering (black rotating scale) to 1.4 mm
  • Cutting the shielding:
    • Set the diameter wheel (silver rotating scale) to 0.8 mm
    • Set the cutting length on the upper wheel while watching the red stop piece's position relative to the linear scale. Set it to 5 mm.
    • Set the centering (black rotating scale) to 1.4 mm (Yes, this is the same setting as for cutting the outer plastic coating!)
  • Cutting the dielectric:
    • Set the diameter wheel (silver rotating scale) to 0.25 mm
    • Set the cutting length on the upper wheel while watching the red stop piece's position relative to the linear scale. Set it to 3 mm.
    • Set the centering (black rotating scale) to 1.2 mm
  • Always set cutting length after setting of cutting diameter, as its setting alters the stop piece position!
