Miniature 8-channel photon counter
id150 SERIES
-
Intended for large-volume OEM applications, the id150-1x8 is the only multichannel solid-state single photon detector on the market. It consists of a CMOS silicon chip packaged in a standard TO8-16pin header with a transparent window cap. The chip combines 8 in-line single photon avalanche diodes that can be accessed simultaneously for parallel processing. square in center-to-center A fast active quenching circuit is integrated within each pixel in order to operate each diode in photon counting regime. The chip is mounted on a printed circuit board on top of a single-stage thermoelectric cooler (TEC). A thermistor can be used to measure the temperature of the chip. Only two low power supplies of +5V and -25V are needed for operation in photon counting mode. The fast active quenching circuit leads to a dead time of less than 50ns per channel. An outstanding timing resolution of less than 60ps allows high accuracy measurements.

Geiger Counters
-
A geiger counter detects nuclear radiation by measuring the emission of ionizing radiation of alpha particles, beta particles and gamma rays. Also referred to as a radiation detector, a geiger counter consists of two main elements: the processing electronics and the geiger tube. The geiger tube is filled with low-pressure inert gas like helium, argon or neon. If radioactive radiation occurs, the inert gas is ionized. An anode within the geiger tube registers the quantity of ionized particles numerically correlating with the strength of the radioactive radiation. The radioactivity measurement is then displayed on the LCD screen of the geiger counter or radiation detector.It is very important to measure radioactivity as well as to classify radioactivity values. For example, terrestrial gamma radiation is measured according to general values from 0.03 - 0.3 µSv/h (microsievert / hour). This "normal" oscillation range is conditioned by natural radioactive elements in the ground such as uranium and potassium. To calculate this factor, one must take into consideration cosmic radiation. For example, when considering cosmic radiation, the maximum radioactivity content at Schneefernerhaus, the highest-located German environmental research station, is approximately equal to 110 µSv/h.At PCE Instruments, you will find three types of geiger counter or raditation detection devices to help you measure radioactivity: 1) alpha radioactivity meters, 2) meters for detecting alpha, beta and gamma radioactivity and 3) radioactivity meters for human beings.
