8. SR-DI/FCT & DCCT FCT and DCCT:
2.5V/A sensitivity for FCT, 0.05V/mA for DCCT (200mA scale).
Higher cutoff frequency for FCT 800MHz (Bergoz) due to big size of the core.
Capacitance of the ceramic and beam shield optimized to meet FCT requirements .
Beam Shield
DCCT Sensitivity (200mA scale)
Final Assembly
FCT higher cutoff frequency

9. SR-DI/FCT & DCCT FCT and DCCT: Share the outer shield and ceramic gap.
Soft Iron for outer shield. 2 layers of Mu metal.
Both are tested in the Lab. DCCT tested in final location by test function
from the electronics with the reading instrument DVM (Agilent 34410A)
and controlled from control room.

15. SR-DI/BLM & SRM BLM: Deal with I-Tech was changed ! (8 BLD and 2 BLM).
Replace 7 BLD (1 BLM) with GDX modules for FOFB.
So 32/64 BPM will be used for FOFB.
1 BLD and 1 BLM are in SESAME, It will be installed in injection section.
The BLM system consists of the signal acquisition electronics (Libera BLM) and the detector. Each of the four input channels provides the power supply and gain control to the photo-multipliers (PMT).
