Temperature Measurement & Control
AdSem, Inc. is a privately held company established in Palo Alto, CA by a group of highly experienced professionals with outstanding achievements in Semiconductors, Radiation Physics, and Material Science.
Our mission is development and production of novel semiconductor materials, advanced semiconductor devices and unique analytical instrumentation for semiconductor, nuclear, and cryogenic industries.
AdSem is the only company in the world that has developed and produce thermistors for any temperature between 1mK and 500ºC.
Our unique semiconductor NTC thermistors measure temperature of everything and everywhere: in-vivo brain and low- temperature radiometers, semiconductor chips and rocket engines.
AdSem is the only company in the world that offers Ge and Si high reflective mosaic monochromators for slow neutrons, gamma – and X-rays. Our mosaic monochromators have neutron reflectivity higher than any other neutron monochromators .
AdSem has invented and developed high temperature Silicon and Germanium NTC thermistors as well as an industrial technology for their production. AdSem opens a new era in temperature sensing industry by bringing up semiconductor technology into the 70-years old market of ceramic NTC thermistors.
There are fundamental scientific reasons for new Si and Ge thermistors to be the most sensitive and
highly interchangeable over working temperature range.
Their features also are:
Widest temperature range;
Micron Form Factor;
Reproducibility of production technology;
Utilization of microelectronic technology & packaging techniques
New doping technology of Ge and Si, developed by AdSem, allows producing unique low-temperature thermistors with wider operating temperature than any cryogenic thermistors, higher sensitivity in any selected temperature range down to 1mK, higher interchangeability at low- and ultra – low temperature and lower price.
For Neutron and X-ray Optics we developed superior technology for production of large Ge and Si mosaic crystalline monochromators. Our monochromators provide the high reflectivity for slow neutrons, gamma-rays and/or X-rays and any mosaicity value up to 1 arc degree.
The areas of our expertise and new development are also:
Novel PTC & NTC semiconductor thermistors with extended working temperatures;
High resistivity silicon;
Radiation technology and neutron transmutation doping of semiconductors;
Novel nuclear methods for non-destructive selection of high quality large crystals;
Advanced semiconductor nuclear detectors;
Advanced Research Systems, Inc. was started in 1986 by Ravi Bains to provide cryogenic solutions for low temperature research.

Cryogenic Control Systems, Inc. (Cryo-con) is a manufacturer of electronic equipment for both laboratory and industrial process control applications. Our mission is to provide the cryogenic industry with high quality, innovative, and technologically superior instrumentation
Cryo-con’s core technical strength is the development and manufacture of cryogenic instrumentation. This often requires the design of unusual circuits that work with the exotic sensors found in some cryogenic systems. However, much more importantly, our products must be made to operate in extremely low noise environments without corrupting any measure of overall system performance.
Cryogenic techniques are frequently used to lower electrical noise in environments where extreme sensitivity is required. If system instrumentation couples electrical noise into such an environment, even at an extremely low level, measurement data can easily be corrupted or destroyed. Electronics designed primarily for room-temperature applications are frequently unsuitable for cryogenic use.
Every Cryo-con product is designed for extremely low noise cryogenic environments. Therefore, the minimization and management of electrical noise is a key element of our design methodology. This requires extensive experience in the use of modern components that must be applied with tested and proven noise reduction techniques.
Cryo-con’s development staff has worked together as a team for over 15 years. Our experience with dilution refrigerators and many-channel SQUID systems is leveraged into our products; which we believe are the lowest noise instruments on the market today.
Digital Signal Processing (DSP) is used to significantly improve performance in a wide range of applications. In Cryo-con’s products, DSP is used to improve measurement accuracy and control stability well beyond limits imposed by electronic hardware. Examples include the signal decimation, lock-in detection and Cubic Spline algorithms used in temperature measurement as well as the signal dithering and enhanced PID used in our control loops
