In this paper we would like to present a few characteristics of the Resistive Plate Chambers (RPC) made of a particular grade of bakelite paper laminates (P-120, NEMA LI-1989 Grade XXX), produced and commercially available in India. This particular grade is used for high voltage insulation in humid conditions. The chambers are tested with cosmic rays in the streamer mode using argon, tetrafluroethane and isobutane in 34:59:7 mixing ratio. In the first set of detectors made with such grade, a thin coating of silicone fluid on the inner surfaces of the bakelite was found to be necessary for operation of the detector. Those silicone coated RPCs were found to give satisfactory performance with stable efficiency of >90% continuously for a long period as reported earlier. Results of the crosstalk measurement of these silicone coated RPC will be presented in this paper. Very recently RPCs made with the same grade of bakelite but having better surface finish, are found to give equivalent performance even without any coating inside. Preliminary results of this type of RPCs are also being presented.Comment: 9 figures, Presented in The 8th International Conference on Position Sensitive Detectors (PSD 2008

“…The glass-based RPCs are found to be more stable mainly for low rate applications, even though some erosion effects are found for such cases, particularly when these are operated in the streamer mode [20]. This has been attributed to the corroding of the glass surface due to the large charge build up in the streamer mode of operation.…”

“…Besides the effect on γ spectroscopy, locating an experiment deep underground strongly influences also backgrounds in charged particle spectroscopy [20] and neutron detection. The latter is an important aspect considering the great interest in neutron sources for s-process in nuclear astrophysics.…”

The goal of nuclear astrophysics is to measure cross sections of nuclear physics reactions of interest in astrophysics. At stars temperatures, these cross sections are very low due to the suppression of the Coulomb barrier. Cosmic ray induced background can seriously limit the determination of reaction cross sections at energies relevant to astrophysical processes and experimental setups should be arranged in order to improve the signal-to-noise ratio. Placing experiments in underground sites, however, reduces this background opening the way towards ultra low cross section determination. LUNA (Laboratory for Underground Nuclear Astrophysics) was pioneer in this sense. Two accelerators were mounted at the INFN National Laboratories of Gran Sasso (LNGS) allowing to study nuclear reactions close to stellar energies. A summary of the relevant technology used, including accelerators, target production and characterisation, and background treatment is given.PACS. 25.60.Dz Interaction and reaction cross sections -26.

“…An RPC is a gaseous detector utilising a constant and unifrom elecrtic field produced by two highly resistive electrode plates like glass and bakelite [1]. These characteristics make both, glass and bakelite RPCs active candidates in various running as well as future HEP experiments for different applications [2]. In STAR experiment at RHIC [3]; ALICE, ATLAS and CMS experiments at LHC [4][5][6]; Belle experiment at KEK are using glass and bakelite RPC based detector systems [7].…”

The evolution of particle detectors dates back to the discovery of X-rays and radioactivity in 1890s. In detector history, the Resistive Plate Chambers (RPCs) are introduced in early 1980s. An RPC is a gaseous detector made up of two parallel electrodes having high resistivity like that of glass and bakelite. Currently several high energy physics experiments are using RPC-based detector system due to robustness and simplicity of construction. In each and every experiment, RPCs have to run continuously for several years. So, it demands an indepth characterization of the electrode materials. In the present study, an elemental analysis of locally available glass and bakelite samples is done using PIXE facility available at Panjab University Cyclotron, Chandigarh. PIXE measurements are done using 2.7 MeV proton beam incident on the electrode sample target. The constituent elements present in these electrode samples are reported.
