Protean Instrument's systems with dual phosphor detectors, ASC-950-DP and MPC-900-DP, now include a cosmic guard detector option. A guard detector should be used whenever the requirement for lower beta background exists. A guard detector lowers beta background by helping to eliminate the interference in a beta measurement caused by cosmic events or background counts. Cosmic background counts are eliminated using electronic rejection in conjunction with a cosmic (guard) detector. The guard detector is of similar construction as the primary sample detector and is mounted such that it will intercept any cosmic radiation seen by the sample detector. Any event detected in the sample detector which is coincident with an event detected in the guard detector is rejected.

The end result of the optional guard detector is a reduced beta background which increases the performance of the instrument dramatically. A system utilizing a guard detector typically reaches the required MDA in approximately half the counting time of a system without a guard detector.

Gas Flow

Protean Instrument uses two types of gas-flow proportional detectors. Both models are designed and manufactured by Protean. These detectors require a steady supply of industrial grade P-10 (10% methane and 90% argon) counting gas. Flow rates vary based on the detector, ranging between 60–150 cc/min at 10 psi pressure.

Pancake Detector

The pancake design is used in the WPC-1050, WPC-1150-Series, and the MDS-Series. It is an ultra-thin window design and must be operated with a window in place.

Hemispherical Detector

The hemispherical detector is designed for windowless operation, but can also be operated with an ultra-thin window in place. The Protean windowless detector is designed for easy cleaning, with a smooth plated interior surface that minimizes trapping points. The detector anode wire can be easily cleaned or replaced by the user without disassembling the shield. The hemispherical detector is used in the IPC-650-Series, MPC-900-GFW, MPC-900-GFL, and the MPC-1000-Series.

Gasless

Protean utilizes a dual phosphor scintillator type detector for applications where portability or gas-free operations are desired. The dual phosphor detector gets its name from the use of ZnS(Ag) that is adhered to a thin disk of plastic scintillator. These detectors are always supplied with an 80 µg/cm² aluminum window. This assembly is coupled to a photomultiplier tube and then encased in a light tight enclosure. All that is required to acquire counts is applied voltage. No gas is required.

The dual phosphor detectors provide excellent alpha-beta efficiency, albeit not at the same performance level of the gas flow detectors. Their portable, gas-free use, however, has made them a popular detector type for performing alpha/beta type measurements. These detectors are currently employed in Protean's ASC-950-DP and MPC-900-DP.
