IceCube--a neutrino telescope that encompasses a cubic kilometer of Antarctic ice at the South Pole, collecting and processing data from 5,160 optical sensors buried a mile deep in the icecap--presents considerable challenges, from overcoming power and bandwidth limitations to simulating the complexities of Antarctic ice, which continue to stretch computing technology. IceCube has faced many computational challenges during its evolution: successfully deploying 5,160 robust, ultralow-power networked computers under 1.5 kilometers of ice; sifting through a terabyte of data daily to cull out just 100 Gbytes of events to send from the SouthPole to the north; processing this data, using sophisticated, CPU-hungry algorithms; and developing satisfactory tools, building appropriate GPU clusters, and managing data to facilitate simulation production. IceCube's success in meeting these challenges is demonstrated by its successful physics results.
Recent development of high speed nuclear emulsion read-out system is remarkable. Motivated by this, we started a project to apply it to studying the interactions of relativistic heavy ions in matter using HIMAC at National Institute of Radiological Sciences in Japan. We have developed the emulsion cloud chamber to study Carbon-Water interaction in the energy range from 400 MeV/n down to several 10 MeV/n. This measurement is quite important from a point of view of the heavy ion therapy. Our experimental results for total and partial charge-changing cross sections at E > 200 MeV/n agree well with the data available from past measurements. Detailed analysis by event-by-event basis is in progress. The new emulsion technology demonstrates the potential to study heavy ion fragmentation.
For the neutrino physics program and for the CBA injection, a new fast extraction system has been implemented to improve the extraction efficiency and the quality of the extracted beam. Central to the new system is a new fast kicker, placed at the H5 straight section, capable of rising between bunches, tr < 170 nsec, and staying constant for 2.6 μsec with flat top ripple less than ± 1.5%. So rar, the system has been operated for longer than 3000 hours and routinely extracts 1013ppp at 99% efficiency. Experiment 745 on QCD test requires a single AGS bunch of 40 nsec. For this purpose another fast kicker was placed at the E5 straight section and powered by a new pulser to produce a half sinusoidal pulse with both a rise and fall time of 200 nsec. A single AGS bunch was extracted through the slow beam channel at 22 GeV/c leaving the remaining 11 bunches undisturbed which continued to be accelerated to 29.4 GeV/c and extracted by the H5 kicker through the fast beam channel. Because the ring circumference ratio of CBA to the AGS is 4-3/4, some of the injected beam from the AGS has to contain 11 bunches instead of 12; consequently, this single bunch extraction mode will also be used for CBA injection.
NEMO (NEutrino Mediterranean Observatory) studies new technologies for the construction of a very large volume (Km3 - scale) underwater detector, devoted to astrophysic neutrino measurements, in the KM3NeT framework: this is a promising tool to better understand the mechanisms that originate the cosmic rays. Muon neutrinos can be detected by identifying and reconstructing the trajectory of the muon generated after the charged current interaction of the neutrino. The newly developed Directional Optical Module (DOM) will solve the ambiguity to identify the direction of the incoming Cherenkov photons. The DOM is based on the new development of a four anodes, 10 inches photomultiplier (PMT) from Hamamatsu Photonics. A light concentrator has been designed to exploit the directional capabilities of the PMT. The new high voltage, low power active bleeder needed to supply the dynodes chain will be presented. An interface to adapt the new device to the standard NEMO data acquisition system has been designed and tested in laboratory. Two complete DOMs will be integrated in the full NEMO tower which will be deployed in Summer 2008 for the NEMO Phase 2 activity in the selected site, at 3500 m depth, 40 miles South East from Capo Passero (Sicily, Italy) in the Mediterranean sea.
Readout electronics for the scintillation bar tracking detector (SciBar) in the K2K neutrino oscillation experiment has been newly developed. Its purpose is to make a readout system for multi-anode photo-multiplier (MAPMT) be compact. A combination of ASICs (VA32HDR11 and TA32CG) is employee to multiplex pulse-height information from each anode of a 64-channel MAPMT and to make a fast triggering signal. A frontend circuit board to be attached to MAPMT is designed to generate biases for ASICs and to relay control signals. A backend electronics module is also newly developed. It is implemented using programmable logic devices and analog devices to generate control signals and digitize multiplexed signals. The system has enough low noise, less than 0.3 photo-electrons and good linearity up to 300 photo-electrons for MAPMTs at the gain of 5/spl times/10/sup 5/.
PARISROC is the front end ASIC designed to read 16 PMT for neutrino experiments. It’s able to shape, discriminate, convert and readout data in an autonomous mode. The digital part manages each channel independently thanks to 4 modules: top manager, acquisition, conversion and readout. Acquisition is in charge to manage the SCA with a depth of 2 for charge and fine time measurement. Coarse time measurement is made with a 24 bits gray counter. Readout module sends converted data of hit channels to an external system. Top manager controls the start and stop of the 3 others modules. The ASIC was submitted in June 2008.
The neutrino oscillation experiment OPERA which will start taking data in 2006 in Gran Sasso National Laboratory (Italy) is now under construction and installation. The most important part of the OPERA detector consists of 62 walls made of nuclear emulsion/lead bricks (total mass of /spl sim/1.7 kton) interlaced with planes of tracking detector (target tracker) which has to provide an information about the location of the neutrino interaction in OPERA detector. The design of the target tracker detector is based on scintillator strips (2.6 /spl times/ 1.0 /spl times/ 683 cm/sup 3/) equipped with wavelength-shifting fibers to transport the light produced by crossing particles to multi-channel photomultipliers. One plane of the target tracker detector (7 /spl times/ 7 m/sup 2/) consists of 256 strips. The mass production of the target tracker modules goes on now at IReS (Strasbourg). About 5700 m/sup 2/ of the detectors will be produced in total during next few months. The design, expected performance, results of the tests and calibration of the target tracker modules as well as some details of the detector production technology are presented.
Generation of relativistic protons in high laser fields provides a source of muon neutrinos with fluxes of /spl sim/ 10/sup 19/ /spl nu//sub /spl mu// s/sup -1/ sr/sup -1/ and energies /spl sim/ 20 MeV. The source is proposed for neutrino oscillation experiments. This paper presents a new concept for a pulsed neutrino source: an Optically Driven Emitter of Neutrinos (ODEN). The generation of neutrinos concludes a chain of events, starting with electron acceleration in laser field, leading in turn to the emission of a proton beam in relativistic regime. The protons generate charged pions, which decay into muon neutrino pairs.
Evidence from astrophysics and particle physics suggest that weakly interacting massive particles(WIMPs) may comprise most of the mass of the galaxy. If these particles exist, they can be detected by cryogenic detectors. The superheated superconducting colloid detector is well suited for use in the search for WIMPs. The earth's motion around the Sun provides a distinctive signal which can be used to confirm a detection.
HiRadMat is a recently constructed facility designed to provide high-intensity pulsed beams to an irradiation area where different material samples or accelerator components can be tested. The facility, located at the CERN SPS accelerator complex, uses a 440 GeV proton beam with a pulse length up to 7.2 μs and a maximum intensity up to 1013 protons / pulse. The facility, a unique place for performing state-of-the art beam-to-material experiments, operates under transnational access and welcomes and financially supports, under certain conditions, experimental teams to perform their experiments.
