In the present R&D, multi-gap resistive plate chambers (MRPCs) are studied for non-destructive inspection of small airport cargos. A six-gap RPC of a line-scan type was constructed using soda-lime glass whose bulk resistivity is measured as 7 x 10^11 Ωcm. The thicknesses of the gaps and the glass plates were 0.55 and 0.52 mm, respectively. The typical detector characteristics such as the...

A cosmic ray telescope equipped with four RPCs of almost 2 m² per plane was constructed at LIP Coimbra in partnership with the Hydronav company (Spain). In view of a possible application for muon scattering tomography, the telescope was tested during several days with high-atomic-number materials, such as tungsten and lead, located at the center of the telescope with two RPCs on each side....

The traditional TOF-PET(Positron emission tomography) mainly uses the structure of a scintillator detector connected to a photomultiplier tube. The structure has the disadvantages that time resolution is not good enough (greater than 50ps), the thickness of the scintillator is large (greater than 3cm), and the reception is small, resulting in a waste of information, long detection time, and...

Muon tomography is one of several fields of applied physics that have witnessed the successful use of particle detection based on Resistive Plate Chambers (RPC). In this work, we will report on an innovative project concerning transmission muography for geological characterization. For this purpose, a muon telescope built of four RPC planes was mounted on an adjustable structure and the...

We present first results from a prototype PET scanner based on Resistive Plate Chambers and specialized for brain imaging. The device features a 30 cm wide cubic field-of-view and each detector comprises 40 gas gaps with 3D location of the interaction point of the photon. Besides other imagery, we show that the reconstructed image resolution, as evaluated by an hot-rod phantom, is...

A new readout scheme allowing the exploitation of Resistive Plate Chamber (RPC) spatial precision and using a limited number of electronic channels is proposed. The new scheme which exploits the spread of the RPC induced charge on several adjacent inter-connected pads, allows the simultaneous detection of several particles without ambiguity.

RPC is a gaseous detector that associates high efficiency, fast timing and good spatial resolution to a cost effectiveness. Large RPC made either of HPL or glass are easily built and successfully operated in several HEP experiments. We propose the use of RPC to perform 3D scans of containers with the help of cosmic rays. In order to have an affordable large scanning system to cover large...
