power is pressure x flow rate (kPa x LPS = watts) or voltage x current (volts x amps = watts) The hydraulic analogy is useful for visualizing what happens in electric circuits, especially the behavior of wires, batteries, resistors, capacitors, inductors, and diodes. There are hydraulic models for each of these circuit components.

All HPGe radiation detectors require cooling to cryogenic temperatures for successful operation. This is typically accomplished using a liquid cryogen, most commonly liquid nitrogen (LN 2 ), or with an electro-mechanical cooler. ORTEC offers a full suite of cryogenic cooling solutions to meet the diversity of customer application requirements.
· the optics system focuses the laser beam and guides it to make head-on collisions with the electron (or positron) beam in the vacuum pipe, after that, the backscattering high energy photon will be detected by the High Purity Germanium (HPGe) detector, which is the key instru- ment of BEMS. The accuracy of beam energy depends

Germanium atom forms four covalent bonds with the four neighboring atoms. Ionic is a type of chemical bond where atoms are bonded together by the attraction between opposite charges. Na₂O. lithium chloride aluminum sulfide To explain, first take a look at the difference between ionic and covalent bonding. tin(IV)oxide copper(II)nitrate .
ISO-KF Hoses / Flexible Connectors. ISO-KF small flange components are manufactured according to DIN 28403 and ISO 2861 in nominal diameters DN 10 to DN 50. ISO-KF connections are suitable for pressures up to 10 -8 hPa and can also be used for over pressures up to 1,500 hPa. With metal seals, the pressure range can be extended to 10 -9 hPa.

· Because germanium has a relatively low band gap, these detectors must be cooled in order to reduce the thermal generation of charge carriers (thus reverse leakage current) to an acceptable level. Otherwise, leakage current induced noise destroys the energy resolution of the detector. Liquid nitrogen, which has a temperature of 77 °K, is the

Examples of some special materials are: Calcium fluoride. Silicon. Sapphire. Steel. Germanium. Dimensional & shape details to individual customer request.
Germanium maintains and improves cellular health (an excellent transporter of oxygen molecules), while Tourmaline channels energy, transforming negative ions into positive, high-frequency ones. Both minerals are distributed throughout the shower hose and are frequently used in natural medicinal therapy.
