Abstract

Recently, the last two modules (out of seven) of the ALICE High Momentum Particle Identification detector (HMPID) were assembled and tested. The full detector, after a pre-commissioning phase, has been installed in the experimental area, inside the ALICE solenoid, at the end of September 2006. In this paper we review the status of the ALICE/HMPID project and we present a summary of the series production of the CsI photo-cathodes. We describe the key features of the production procedure which ensures high quality photo-cathodes as well as the results of the quality assessment performed by means of a specially developed 2D scanner system able to produce a detailed map of the CsI photo-current over the entire photo-cathode surface. Finally we present our recent R&D efforts toward the development of a novel generation of imaging Cherenkov detectors with the aim to identify, in heavy ions collisions, hadrons up to 30 GeV/c.

Small but Tubby: A Magnetic Loop Antenna Made from 100 mm Copper Tubing

This paper presents the electrical model, key equations, and practical construction of a small transmitting magnetic loop antenna built from unusually large 100 mm diameter copper tubing. The large conductor surface area and wide-area transitions to the vacuum capacitors were designed to minimize resistive losses. The frequency range from 1.8 MHz to 31 MHz is unusually wide. Frequency, impedance matching, and azimuth are all adjusted automatically by servo motors. Indoor losses originate predominantly from near-field coupling to the environment rather than from the antenna itself. Temperature-rise measurements confirm that the bulk of the dissipated power is absorbed by the environment, not by the antenna components. The conducted H-field measurements demonstrate good agreement between the measured H-field and the theoretical free-space H-field calculated from the antenna geometry and an estimated loop current. The loop current was estimated from the measured antenna bandwidth and the applied transmit power. The antenna was developed for indoor operation where outdoor installation is not possible.

Triaxial $μ$-PIC for resolving Multi-Hit Ambiguity

The micro pixel chamber ($μ$-PIC), a type of micro-pattern gaseous detectors (MPGD), features pixel electrodes structured similarly to a sliced proportional counter. Conventionally, $μ$-PIC electrodes are connected to orthogonal strip electrodes to reduce the number of readout circuits; however, this configuration introduces multi-hit ambiguity when tracing winding tracks or during high-rate operations. A well-known solution to this problem is the adoption of an additional readout axis. To this end, we designed a new electrode structure using Garfield++ simulations and fabricated a triaxial $μ$-PIC based on through-glass-via (TGV) technology. This triaxial $μ$-PIC achieved a high gas gain of $1.1\times 10^4$ and the energy resolution of 22\% (FWHM) at 5.9~keV, Furthermore, the false-hit probability was less than 0.78\% at a 95\% confidence level for two clusters separated by a distance of over 3 mm, consistent with Garfield++ predictions. With this triaxial $μ$-PIC, single avalanche signals are collected from three independent readout strip electrodes (the anode and two cathodes). The charge ratio among these electrodes remains nearly constant at anode:U-cathode:V-cathode=3:2:1. In addition, we successfully achieved an enhanced gain of $3.2\times 10^4$ without increasing the discharge risk by employing an alternative operation mode.

Experimental Characterization of Bulk Micromegas for Development of Active Target Time Projection Chamber for Nuclear Astrophysics Studies

A Micromegas-based active target Time Projection Chamber, namely Saha Active Target TPC (SAT-TPC), is under development at Saha Institute of Nuclear Physics for its application in nuclear astrophysics experiment to measure the branching ratio of the direct and sequential decay of the Hoyle state of $^{12}$C. A bulk Micromegas was characterized to optimize its operating parameters and its performance for $α$-particle tracking was investigated using gas mixtures Ar + CO$_{2}$ (90:10) and Ar + i-C$_4$H$_{10}$ (95:5) at atmospheric pressure using 5.9~keV X-ray and 5.48~MeV $α$-particles from radioactive sources. A hydrodynamic transport model was used to simulate the charge-deposit profile of the $α$-particle track on the Micromegas readout and compared to the experimental data to complement the experimental measurement as well as validate the numerical model. A good agreement was observed that confirmed the suitability of the choice of the bulk Micromegas in the development of the SAT-TPC prototype and the hydrodynamic modelling of the detector dynamics
