S4 — Ioncatcher Degrader System

FRS Home Page - Areas.gif S4 Pictures Drawings Cable Connections

Updated May 6th, 2022.  

The ioncatcher degrader consists of:
  • two ladders (GHFSEM1GL from below and GHFSEM1GR from top) for fixed plates,
  • a double wedge vor variable thickness (GHFSED4 from below and GHFSED5 from top)
  • two wedge shaped disks for variable angle (drive in / out = GTS3ED7DP), rotation still on extra controller .

Sorry, the two wedge-shaped plates and the two wedge-shaped disks are not yet integrated into the online calculator, use EXCEL sheet instead.

The key parts are:

On ladders:
2018 wedge-shaped plates from Hallstein&Heyl (AlMg3 rho = 2670 mg/cm3):
  • 2 to 8 mm Al wedge   "Keil-2": slope = 0.01691, deviaton from plane sigma_z = 30 um
  • 2 to 18 mm Al wedge "Keil-2": slope = 0.01750, deviation from plane sigma_z = 6.2 um
  • 1.5 mm Ta plate
  • 3.0 mm Ta plate

Double wedge:
2012 ion catcher degrader plates:
  • plate 1 (from Kugler): slope = 39.94 mg/cm3, central thickness= 1164 mg/cm2
  • plate 2 (from Kugler): slope = 40.02 mg/cm3, central thickness= 1158 mg/cm2

Wedge-shaped disks:
2012 ion catcher degrader disks:
  • disk 1 (new from ESS): slope = 24.62 mg/cm3, center thickness= 482.2 mg/cm2
  • disk 2 ( from Kugler): slope = 24.68 mg/cm3, center thickness= 510.0 mg/cm2

How to use:
  1. Switch on (on back side)
  2. starts in standby, press button [standby] (wait ~ 1min)
  3. select [Home] in menue on screen
  4. select axis-number = 0
  5. select "absolut" motion
  6. enter new value with number keys and press [valid]
  7. press [exec]
