Ponena za kupanga zinthu zoyezera kutentha, makamaka Molecular Beam Epitaxy (MBE), kusunga malo otentha kukhala olimba ndiye chinthu chofunikira kwambiri. Ngati mukufuna makristalo oyera komanso zigawo zofanana, pali'Palibe njira yopewera vutoli. Ku HL Cryogenics, tikudziwa kuti vuto lenileni la kukula kwa Gallium Nitride (GaN) limadalira momwe mumalamulira bwino kuperekedwa kwa nayitrogeni yamadzimadzi (LN).₂) kwa ma cryoshroud. Icho'masewera a kulondola—Dontho lililonse liyenera kukhala lopanda madzi ozizira, mpaka pomwe likufunika. Ngati mpweya uliwonse wa nayitrogeni walowa—nthawi zambiri chifukwa cha kutentha komwe kumalowa mkati panthawi yosamutsa—mumapeza malo otchuka ndipo“kulavulira"mkati mwa chipinda cha MBE. Kuti'Nkhani yoipa ya khalidwe la filimu ya GaN.

Kuti tisunge kuchuluka kwa vacuum kumeneku kukhala kolimba kwa zaka zambiri, timadaliraDongosolo la Pampu Yopumira Yopanda MphamvuIcho'Nthawi zonse timayang'anira ndikusunga kupanikizika mu jekete la vacuum, kuti chotenthetseracho chisakulepheretseni. Kuti tiwongolere kuyenda kwa madzi, timagwiritsa ntchito Vacuum Insulated Valve yathu yopangidwa mwaluso. Imaletsa kufupika kwa kutentha ndi kusonkhana kwa ayezi pa tsinde, ndipo imakupatsani kutseka kolimba komanso kutseka bwino, ngakhale pa -196°C.
Ngati mukufuna malo osungiramo zinthu m'malo osiyanasiyana kapena malo osungiramo zinthu, Mini Tank yathu yapangidwa kuti ikhale yolimba kuti igwiritsidwe ntchito ndi ma netiweki a cryogenic oyera kwambiri. Makina athu amapezeka kulikonse.—ganizirani zoyesa ndege, malo oyesera zamankhwala, malo akuluakulu oyeretsera magetsi a LNG, ndi zipinda zotsukira zamagetsi—chifukwa kudalirika sikungakambirane. Timagwiritsa ntchito chitsulo chosapanga dzimbiri chapamwamba kwambiri ndipo timayang'ana kwambiri kuonetsetsa kuti chilichonse chikuyenda bwino komanso mosamala.

Ku HL Cryogenics, timadziwa kuti gawo lililonse la mzere wosinthira wa cryogenic liyenera kugwira ntchito bwino kuti kukula kwa GaN kuyende bwino.
