Electrode sequence:
- 1.1 cooper foil covered glass - cathode
- 0.3 nylon fishing line
- 1.1 glass plate (supporting the spacers)
- 0.3 nylon fishing line
- 1.1 glass plate
- 0.3 double faced strip readout plate
symmetry plane
Readout electrode:
- support:0.3mm tick pcb plate
- 16 gold coated strips on each side
- pitch: 1.27 mm, 1.00 mm strip width,
1.54 mm gap width
Sizes:
glass electrodes: 46 x 900 mm2
readout plate: 0.3 x 46 x 980 mm3
housing: 40 x 80 x 960 mm3 Al box
Last week results: U=- 6.5 kV, 60Co source
standard gas mixture: C2F4H2/isobutene/SF6 85/5/10
Where we are? Needs
- the prototype works
- the first estimates on the time
resolution using 60Co source will
be obtained in the next couple of
weeks
Short term plans
- In beam tests @ GSI-Darmsatdt
April-May within FOPI
Collaboration - to be discussed
- 2 -2.5 GHz scope
- one more TDC2228A
- two 2249W ADCs
- 2-3 CF4000 discriminators
