BPM ID Komplett | Additional equipment for BPM, LoCuM-4 and Cables

Technical Description:

In addition to the Beam Position Monitor,
FMB offers the necessary additional equipment for installation of complete BPM-units:

1. The BPM chamber

  • FMB standard solution or according to customer’s specification
  • material: 1.4301 or 304, option: 316LN (flanges)

2. The underframe (column)

  • massive standard column, filling with sand is recommended
  • insulation against variations in temperature
  • special design according to space requirements is possible

3. The LoCuM-4 with cables

  • for analysis of the detected photon currents
  • four-channel low-current monitor and current-voltage converter
  • simultaneous determination of the four independent photocurrents between 100 pA and 1mA
  • controller for internal switch function – remote mode via RS232
  • special double-shielded measurement cable (length about 20 m) is recommended

4. Pinhole Array

  • with frame
  • installation in dipole BPM

5. Appropriate bellow

  • welded bellows ( about 20 membrane pairs (DN35CF) and 30 membrane pairs (DN63CF) ) for motorized stages
  • hydroformed bellows for manual adjustment

6. The motorised H-V-Stage

  • adjustment of the complete pre-set BPM into its accurate measurement position within the Beamline
  • high precision and compactness
  • with stepper motor
  • encoder is recommended, but manual operation is possible (necessary mechanical limitation is installed)
