PIPS Detector

FD series detectors are mainly used in α and β particle energy spectroscopy measurement which is the standard detector of charged particle spectrometers.

It is a high resolution, high sensitivity and low background Alpha detector. To ensure high resolution, the energy deposition of Alpha rays in the sensitive volume must be maximized. The energy deposited in the sensitive volume deviates from the energy of the Alpha ray due to partial energy loss when charged particles interact with the material of detector`s incidence window. And the can thin window on the detector surface reduces the loss of energy in the incidence window. In addition a low level of leakage current reduces the contribution of electronic noise.

CAM series detectors are suitable for continuous air α and β particle detection, offline measurement filter sample measurement, mainly used in radon detectors and aerosol detection;

It is for continuous air monitoring in harsh conditions and is an enhanced version of the standard CAM detector. The detectors are micromanipulated with an inert coating of controlled thickness in the presence of a surface-thick aluminum layer. The coating provides excellent acid resistance and non-scratch properties. It is thinner than conventional aluminium layers, reducing the occurrence of conditions such as particle flashing. And it is suitable for measurements in harsh conditions, such as offshore or stack applications.

Passivated Implanted Planar Silicon detector（PIPS Detector) is a product of modern semiconductor technology. It used ion implantation device to accelerate ions, after screening, focusing and re-acceleration, they are injected into silicon wafers. The whole process is carried out under vacuum. The production of deep ion-implanted silicon detetcors for alpha/beta spectrometers have undergone thousands ofapplictaion so far, including alpha and beta energy spectrum analysis and counting, nuclear identification, environment radiation monitoring and many other relevant fields.

Compared with the Silicon surface-site-barrier detectors (SSB) and Diffuse Junction-type detectors (DJ), PIPS detector has the following advantages:

1. All structural edges are buried inside and do not require the use of epoxy sealers；

2. The entrance window is sturdy and durable, easy to clean and wipe；

3. In order to reach better energy resolution, Contacts are precisely formed by ion implantation and are thinner；

4. Leakage current is usually 1/8 to 1/100 of SSB and DJ type detectors；

5. The thickness of the entrance window is smaller than that of the corresponding SSB and DJ type detectors；

6. Standard detector can be baked to 100°C；

We can provide two types of PIPS detectors: Continuous Air Monitoring Planar (CAM) series and Fully Depleted (FD) series.

Both kinds of detectors can adapt to normal or vacuum environment, in addition the entrance window of probe has an aluminum protective film. The output connector are using Axial Microdot female, BNC and SMA for the options.
