MINIBALL – T-REX

MINIBALL – T-REX. Beam requirements: - slow extraction … as long as possible pulses from EBIS - high duty cycle … will not change with EBIS - beam spot size: < 3 mm (FWHM) … as currently or better - beam spot should be centered on target

Presentation Transcript

  1. MINIBALL – T-REX Beam requirements: - slow extraction … as long as possible pulses from EBIS - high duty cycle … will not change with EBIS - beam spot size: < 3 mm (FWHM) … as currently or better - beam spot should be centered on target … currently sometimes not the case - energy definition … not so critical / energy straggeling in target - micro structure has neither been used nor has been requested … to my knowledge

  2. MINIBALL – T-REX Power consumption (current situation, peak power): plus 3 pump stations (500 W each) To design the installation numbers should be multiplied by 2 to be on the safe side Thanks to Roman Gernhäuser

  3. Spectrometer Examples of existing or planned spectrometers of the types we may would like to have one: RITU (thanks to Juha Uusitalo) - 4 magnets (QDQQ), power consumption 120 kW at most - beam spot size not critical, 5 mm desirable MARA (thanks to Jan Saren) - configuration QQQEDMD, total power consumption 100 kW at most - beam spot size: 2 mm at most (dispersive plane) … critical! 3-4 mm (non-dispersive plane) EMMA (thanks to Barry Davids) - less than 200 kW if all elements are fully powered, e.g. pumps not included - 1 mm beam spot size … critical! No TOF, therefore micro structure not important High instantaneous rate is serious problem for all focal plane detectors Energy resolution of beam has not been discussed
