Muon detector systems

Complete system

Our muon counters are delivered as a system, complete with all hardware and software. They are quick to set up and easy to use.

One-paddle system

This lowest-cost system will detect cosmic muons, display photomultiplier pulses, measure muon arrival times and even observe muon decay and measure the muon life time accurately.

Its muon detector consists of a 10" by 8", 1-inch thick scintillator paddle with a solidly integrated 2-inch PMT inside a magnetic shield and protective housing.

For highest safety, the PMT is powered by a plug-on HV supply (TwinBase). There is no high-voltage carrying cable in this sytem.

All data acquisition is accomplished by a tiny eMorpho unit (2" x 2"). It connects to a PC or laptop via a single USB cable. The PC controls and powers the eMorpho, and the eMorpho controls and powers the TwinBase.

Two-paddle system

This full-featured system can measure the direction- dependency of the cosmic muon flux by recognizing the coincidence between two paddles.

Its components are those of a one-paddle system plus an X-ADC card which is used to convert the single-channel eMorpho into a two-channel data acqusition and signal processing unit.

Its software reports singles and coincidence rates, display singles and coincident photomultiplier pulses on screen and creates and shows pulse height spectra.
