HPGe innovation: electro-mechanical cooling from Ortec with resolution performance of a nitrogen cooled detector

The Integrated Cryocooling System (ICS) from ORTEC is a highly innovative development in the field of cooling for HPGe detectors. The traditional disadvantages of using a HPGe detector are addressed: refilling nitrogen and mechanical cooling (microphonic / reliability) are overboard. In addition, the cured cryostat by a full warm-up cycle is needed.

This simplification has the resolution of a HPGe detector with the convenience of a scintillation detector!

benefits

• Without liquid nitrogen cooling;
• No reset of the warm-up cycles by vacuum hardened cryostat;
• installation in any orientation.

characteristics

• Typical cooldown time six hours (60% rel eff detector);
• AVC (Active Vibration Cancellation): virtually no microphonics, resolution comparable to nitrogen;
• Reliable: 200,000 MTTF for Sterling cooling;
• Quiet: less than 60dB

product comparison

To illustrate how the ICS compares to comparative devices (read: Dewar, X-Cooler III and Mobius), we have a product comparison. This way, you simply select the cooling which best suits you.

	Dewar	X-Cooler III	Mobius	ICS
Refrigeration	LN2 refill weekly, dangerous and costly	Compressor	LN2 & Sunpower Cryocooler, LN2 refill once in two years	Sunpower cryocooler
Employability	All detectors, PopTop and conventional cryostat	All detectors, PopTop and conventional cryostat	All detectors, PopTop and conventional cryostat	Conventional cryostat, Poptop follows. GEM, GMX Profile and GLP series
Up time	Depends on refill	Replacement unit immediately dispatched within two year warranty	Cryocooler MTTF > 200.000uur, LN2 back-up on failure	Cryocooler MTTF > 200.000uur. Hardened cryostat no warm-up cycle
Resolution performance	Very well	Under 500keV resolution degradation is less than 10% compared LN2	Under 500keV resolution degradation is less than 10% compared LN2	Very well by Active noise cancellation
Flexibility placement	Restrictions by size Dewar	Very flexible in placement by external compressor	Equal to 30L Dewar	Placement in any orientation, optional pneumatic position for placement in lead castle
