BPM ID Komplett | Motorised H-, V- Stage 10 / 10 Column , LCAD and Cables

Technische Beschreibung:

The well-known Beam Position Monitor (BPM)- inserts, described in our datasheets, are preferably to be installed into a complete BPM -unit.
Complete BPM-unit consist of:

  • the BPM-chamber
  • the motorised H- V – Stage and
  • the under frame (column).

The motorised H-V-Stage was developed by FMB.
The unit is able, to adjust the complete pre-set BPM into its accurate measurement position within the beam l ine. Especially the high precision and compactness of the X-Z-stage are remarkable. If required an additional encoder (Manufac turer: AMO, Austria) can be installed in every direction (inside of the stage). As an additional option FBM offers implementation of another special types
of encoder (for example: SLS/PSI). Furthermore, the manual opera tion of the stage is possible. Necessary mechanical limitations are installed.
For a complete package BPM we provide as an under frame a massiv e standard column, which we can fill with sand, too. It is possible to insulate the column against variations in temperature. Customers space conditions can be considered. In this case, the under frame will be designed accordingly.
For the analysis of the detected signals we provide the suitable electronic device LCAD 4 (four channel Low Current Asymmetry Detector). The Low Current / Voltage- Converter LCAD 4 is a useful instrument for the simultaneous determination of the four independent photocurrents between 1nA and 1mA. The beam position can be precisely obtained from the asymmetry of the
measured photocurrents. The generated currents on the blades flo w via double-screened measuring cable into the 4 channels of the LCAD 4, where they are converted into proportional voltages. All 4 measurement circuits are closed to the earth potential via a switchable BIAS- voltage (between +/-280 V - included in this device).
The manufacturer of the LCAD 4 is Messrs. GMS Frank Optic Products GmbH, Berlin. Delivery also includes the special doublescreened measurement cable (length about 20 meters).
