Measurements of neutron streaming through penetrations in biological shields are being carried out at JET fusion device by means of thermoluminescence (TL) detectors with the objective to validate the neutronics codes and nuclear data widely applied in ITER nuclear analyses in a real fusion environment. TLDs response due to the neutron component of the radiation field is related to the neutron fluence in a well-defined neutron energy spectrum. Therefore, a TLDs calibration in real fusion radiation fields is necessary to allow neutron fluence from TL measurements at JET to be more precisely calculated. Hence, a MCP-N and MCP-7 TLDs produced at the IFJ PAN in Kraków were calibrated at the ENEA facilities of Frascati and Casaccia laboratories. The obtained results have been analysed and new calibration factors are proposed. The detection system based on TLDs developed and calibrated for JET experiments can then be generally applied not only to fusion neutron fields, but also to ITER to monitor the neutron fluence outside the biological shield.

The Global Calorimeter Trigger (GCT) is a device which uses data from the CMS calorimeters to search for jets, produce isolated and non-isolated electron lists and compute all the transverse and missing transverse energy sums used for the Level-1 trigger decision (L1A). GCT performs these functions by receiving and processing the data from the Regional Calorimeter Trigger (RCT) and transmitting a summary to the Global Trigger (GT) which computes the L1A decision. The GCT must also transmit a copy of the RCT and GCT data to the CMS DAQ. The vast amount of data received by the GCT (230 Gb/s) as well as the necessity for data sharing required by the jet finder impose severe constrains on the GCT design. This paper presents an overview of the revised design, in particular, the algorithms, data flow and associated latency within the revised GCT.

Assuming lepton universality, Mz = (91.182 ± 0.009exp ± 0.020L: P) GeV, Γz=(2484 ± 17) MeV, σhad 0=(41.44±0.36) nb, and Γhad/Γℓℓ=21.00±0.20. The corresponding number of light neutrino species is 2.97 ±0.07. The forward-backward asymmetry in leptonic decays is used to determine the ratio of vector to axial-vector coupling constants of leptons: gV2(MZ2)/gA2(MZ2)=0.0072±0.0027. Combining these results with ALEPH results on quark charge and b b¯ asymmetries, and τ polarization, sin2θW(MZ2) =0.2312±0.0018. In the context of the Minimal Standard Model, limits are placed on the top-quark mass. Reprinted by permission from Springer Nature: ALEPH Collaboration (D. Decamp et al.), Z. Phys.

The CMS electromagnetic calorimeter consists of about 76000 lead tungstate crystals. A brief description of the readout electronics chain of the calorimeter is given. About 15000 Very Front End (VFE) cards amplify, shape and digitize the signals of the photo-detectors attached to the crystals. The production and the test program for these VFE cards are presented. The test program includes the power on test, the burn in and the calibration of the read out channels. Preliminary results of the tests performed on 420 pre-series VFE cards are presented.

The COherent Muon to Electron Transition (COMET) experiment aims to search for the neutrinoless muon to electron transition process with new sensitivity levels. The online trigger system is an integral part of achieving the sensitivity levels required and will be subject to an expected neutron fluence of up to 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">12</sup> n ·cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-2</sup> within regions inside the detector solenoid. Consequently, a significant number of soft errors in the logic of the onboard field programmable gate arrays (FPGAs) can occur, requiring error correction for single event upsets and firmware reprogramming schemes for unrecoverable soft errors. We studied the radiation tolerance of the COMET Phase-I front-end trigger system, called COMET TRIgger (COTTRI), subject to neutron fluence on order 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">12</sup> n ·cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-2</sup> with multiple error correcting codes and automatic firmware reconfiguration. The regions measured were the configuration random access memory (RAM), block RAM (BRAM) and also in a multigigabit transfer link using copper cables that will be used for communication between different trigger boards during Phase-I. The resulting cross sections observed suggest the most significant impact to the experiment will come from unrecoverable soft errors in configuration RAM (CRAM), with dead time expected to be 4.2% ± 1.3%. The effect of multibit errors in BRAM was found to be almost negligible in COMET Phase-I. In addition, multiple solutions have already been proposed in order to suppress these errors further. Soft errors observed in the multigigabit transfer links were measured to be of two orders of magnitude less impact compared to the unrecoverable errors in CRAM. We concluded that the COTTRI system meets the trigger requirement in COMET Phase-I.

This thesis presents a measurement of the Z{sup 0} Boson resonance parameters. The measurement was performed at the Stanford Linear Collider using the Mark II detector. Based on a sample of 480 Hadronic and Leptonic decays, the mass is found to be 91.14 {plus minus} 0.12 GeV/c{sup 2}, the total width is 2.42 {sub {minus}0.35}{sup +0.45} GeV, and the peak cross section for all Hadronic events, and for Muon and Tau events with cos{theta}{sub Thrust} < 0. 65 is 45 {plus minus} 4 nb. By constraining the visible width to the Standard Model value for 5 quarks and 3 charged leptons, and allowing the invisible width to be a parameter, the width to invisible decay modes is found to be 0.46 {plus minus} 0.10 GeV. Assuming this width comes from massless neutrinos, this measurement corresponds to 2.8 {plus minus} 0.6 neutrino species. This measurement sets an upper limit of 3.9 neutrino generations at the 95% confidence level, ruling out a fourth generation of Standard Model neutrinos at this level. 54 refs., 65 figs., 11 tabs.

Abstract Results are presented on the decrease of the scintillation light output of long bismuth germanate (BGO) crystals at room temperature due to irradiation by 60 Co photons and 25 MeV electrons with doses from 50 to 5000 rad. After irradiation the light output recovers spontaneously. This recovery can be described by the sum of a minimum of three exponential functions. The shortest time constant is of the order of several hours, while the longest time constant is several hundred hours. The initial decrease in light output depends non-linearly on the dose applied and saturation effects have been observed. The damage induced by irradiation with 25 meV electrons is similar to the damage caused by 60 Co photons. The data are consistent with the view that only the absorption properties of BGO are changed by irradiation. For comparison, a NaI(Tl) crystal and a CsI(Tl) crystal have also been irradiated. Also, the effects on light transmission due to radiation damage to BGO are reported.
