The ALMA front-end cryostat is a cylinder 1-m in diameter and 0.5-m high which holds up to 10 receivers operating in different frequency bands for full details see [1]. Figure 1 shows the cryostat in a preliminary mounting frame which allows initial RF measurements to be made using the adjacent electronics and control racks. Figure 2 shows a close-up picture of the top of the cryostat with the ...

Here we describe a bench-top cryostat system to control the temperature of liquid ethane in a cryo-plunge apparatus designed for biological specimen preparation for electron cryomicroscopy. It comprises a foam insulated Dewar containing a copper cryostat cup, whose temperature is controlled via an active feedback system to within 0.1 K. The device can easily be incorporated into existing manual...

The quality of microscopic image of cryostat sections that had been subjected to microwave assisted fixation was compared with that resulting from conventional air drying of the sections. The role of microwaves in producing rapid special stains on cryostat sections was also assessed. Methods used permitted stains such as periodic acid Schiff, alcian blue, Gordon and Sweets's reticulin, Masson F...

A fluorescein isothiocyanate (FITC) technique and one based on peroxidase-antiperoxidase (PAP) were used to study the distribution of immunoglobulin (Ig) in cryostat and paraffin sections of human tonsil. Trypsin and other proteolytic enzymes were used to 'unmask' the antigen in paraffin sections. The effects of processing, and particularly of fixation, on the immunohistochemical response of ti...

As an insertion device, the superconducting wiggler has been developed for about 40 years, magnet of which is usually made NbTi and set in a cryostat. The performance cryostat vital to success wiggler. In this paper, with 32 poles 2.6 T field High Energy Photon Source Test Facility (HEPS-TF) was Institute Physics (IHEP). cryostat, novel design thermal structure cooling capacity distribution pro...

LEGEND is the next-generation experiment searching for neutrinoless double beta decay in 76 Ge. The first stage, LEGEND-200, takes over cryogenic infrastructure of GERDA at LNGS: an instrumented water tank surrounding a 64 m 3 liquid argon cryostat. Around 200 kg Ge detectors will be deployed cryostat, with acting as cooling medium, high-purity passive shielding and secondary detection medium. ...

A bone cryostat is described with which cold sections of unfixed, undemineralized calcified tissue can be prepared. The bone cryostat is suitable for the preparation of the sections required for the histochemical and immunofluorescent study of bone, for electron microprobe analysis, and for bone and joint autoradiography with soluble compounds.
