9. Recent developments: other
Control System:basic version almost ready – see other presentation
Cabling
Web readout: not quite done yet
Organization in racks
spectrometer electrodes & top chamber designed
electronic magnet-system readout/control

10. The next 12 months Top chamber & electrode structure
Trapping tests: ion source and stable rextrap bunches
Some sort of recoil spectrum
Optimization
Simulations/preparations for long-term improvements
Tendering of electrode structure is going on via cern now
Fill gaps/expand Ctrl Sys (due to rapid development)

11. Ideas for future improvements: Cryogenic Traps
Biggest contribution to response function width: thermal motion in traps!
We’ll be looking
carefully at SHIPTRAP!

12. Ideas for future improvements: A Tape Station used in a new way
Since recoil nuclei are counted directly in an MCP, that detector will be contaminated  only decays leading to stable daughters can be studied.
Solution: tape station for secondary e-creation
WE SOMETIMES SAY IN THE WITCH GROUP THAT WE ARE TAKING THE STEP TO A GENERAL RECOIL SPECTROMETER. In the present version that is not true.
We also think of doing some developments to allow TOF measurements of spectra
x kV
ion e-
mcp
Tape station

13. Summary
Several developments have been finished recently, and few remain as we approach a period of systematic tests
WITCH will be doing systematic trapping tests, and possibly get some sort of recoil spectrum this radioactive-beam period
2004 will show the principle with decent precision, the set-up and method will be refined and potentially present limits on ”a” will be reached
After 2004, or so, larger upgrades of WITCH might be started
