(Hadron Velocity Measurement Device)

Internationale Veröffentlichungsnummer: (Patent Number): WO002014202499A1

The device allows non-destructive measurement of ion beam energy with absolute precision down to 0,1 %. Calibration with a high precission electron gun allows compensation of temporal deviation.

Device allows manual and remote operation of valves and automatic closing in case of interlock

Usable for switching ohmic or inductive loads (either 60 V / DC: 3 A or 125 V / AC1: 125 VA; AC15: 25 VA)

• open / close (on / off) buttons for manual usage
• indication of valve position (position switches) via LED
• 3 different interlocks for pressure in chamber A, B and independent one
• interlock signals are isolated mirrored and output
• no self-opening of valve
• remote in- and outputs for controlling the valve and reading its position and general interlock
• remote controlling of the valve via closing contact or 0-5 V signal (internal switch)
• all inputs and outputs optically isolated (outputs: open collector)
• buttons signals are executed prior remote signals
• restart lockout after power failure of internal or external supply
• different supply circuit for logic and isolated inputs / outputs
• separated and customizable supply for external load
• selectable pull-up resistors for outputs: open, close, general interlock

• contains silicon box detectors, preamplifiers, cooling
• compact design, light weight, transportable
• separated cooling of detectors and electronics
• allows close mounting of germanium detectors

• controls the safety cup and "Strahlanforderung"- signal depending on user action and interlock condition
• prevents the cup from damage by frequently occurrence of interlock signals
• provides secure "Beam off" condition
• shows the position of the safety cup

• calculates and shows the ion beam energy in MeV/u on seven segment display
• normalizes counted events depending on beam intensity
• scans magnetic fields within an adjustable range by applying specific currents
• provides start, stop as well as gating functionality in case of low beam intensity
• works in 4 different user selectable operating modes
• counts events, saves average values and transmitts eventdata to a PC

• synchronizes the target wheel to an external puls with a maximum deviation of +-200µs @ 18,67 Hz rotating speed
• mean deviation is about +-30µs @ 18,67 Hz rotating speed
• works in 2 user selectable speeds
• provides safety functionality: wheel blocked, wheel too fast/too slow, wheel not starting, puls failure...
• provides increment encoder position signals

• replaces damaged motor control board of Bruker magnet power supply
• consists of up-to-date power circuits
• provides manual motor control
• shows status of motion
• compares desired and actual value and generates interlock condition (not used)

• controlling a current source to systematically scan targets in rotating direction expand the Target Online Diagnosis System of R. Mann and calulates high detailed 3D images of targets while experiment is running
• Resolution in shown image
  
  • horizontal: 10 µm
  • vertical: 180 µm
  • thickness: < 0,5 nm
