PM and Bragg cell connections
Warning Switch off the processor before connecting cables to it.
Do not hold the photo-multipliers by hand when the high voltage is switched
on.
The number of channel and the way to connect depend on the system
configuration. The following table gives the different configurations:
Configuration 1 PM aux. 2 PM aux. 3 PM aux. 4 PM aux. 5 PM aux.
LDA 1D U1
LDA 2D U1 U2
LDA 3D U1 U2 U3
PDA fiber 1D U1 U2 U3
PDA fiber 2D U1 U2 U3 V
PDA fiber 3D U1 U2 U3 V W
PDA dual 2D U1 U2 V2 V1
PDA dual 3D U1 U2 V2 V1 W
PC connection
• Connect the 57X08 photomultiplier to connectors High Voltage, PM
Aux. and PM In. Each velocity channel has its PM Aux connector in the
upper half of the rear panel, and three connectors in an input module in
the lower half. A label at the right hand side of the rear panel indicates
the connector names.
• Connect the Bragg cell to the connector Bragg Cell 40 MHz in the upper
left. If your optical system requires a different Bragg dell drive
frequency, the connector Bragg Cell Var. can be used. This output does
not include DC supply to the Bragg cell amplifier, which must be
supplied from elsewhere.
• To connect the PDA receiving optics to the detector unit, please refer to
chapter 7.5 of this manual.
• To use a DualPDA detector unit and optics in FiberPDA configuration,
please refer to chapter 7.5 of this manual.
• Mount the Ethernet card supplied with the BSA in a free slot in the PC,
and install its driver.
• Connect the supplied point-to-point Ethernet cable between the RJ42
connector and the Ethernet network interface card in the PC.
Shutter and optical fibre connection (for PDA measurements only)
• Connect the BNC cable between shutter connector on the detector unit
and the connector Programmable output 2 on the processor.
• Connect the calibration optical fibre between the Cal. Input on the
detector unit and the Calibration Fibre Connector on the processor.
