This paper reports on a SOI detector with drift field induced by the flow of majority carriers. It is proposed as an alternative method of detector biasing compared to standard depletion. N-drift rings in n-substrate are used at the front side of the detector to provide charge collecting field in depth as well as to improve the lateral charge collection. The concept was verified on a 2.5 ×2.5mm2 large detector array with 20 μm and 40 μm pixel pitch fabricated in August 2009 using the OKI semiconductor process. First results, obtained with a radioactive source to demonstrate spatial resolution and spectroscopic performance of the detector for the two different pixel sizes, will be shown and compared to results obtained with a standard depletion scheme. Two different diode designs, one using a standard p-implantation and one surrounded by an additional BPW implant will be compared as well.

Because of their penetrating power, energetic neutrons and gamma rays (∼1 MeV) offer the best possibility of detecting highly shielded or distant special nuclear material (SNM). Of these, fast neutrons offer the greatest advantage due to their very low and well understood natural background. We are investigating a new approach to fast-neutron imaging — a coded aperture neutron imaging system (CANIS). Coded aperture neutron imaging should offer a highly efficient solution for improved detection speed, range, and sensitivity. We have demonstrated fast neutron and gamma ray imaging with several different configurations of coded masks patterns and detectors including an “active” mask that is composed of neutron detectors. Here we describe our prototype detector and present some initial results from laboratory tests and demonstrations.

Monolithic Active Matrix with Binary Counters (MAMBO) is a counting ASIC designed for detecting and measuring low energy X-rays from 6–12keV. Each pixel contains analogue functionality implemented with a charge preamplifier, CR-RC2 shaper and a baseline restorer. It also contains a window comparator which can be trimmed by 4 bit DACs to remove systematic offsets. The hits are registered by a 12 bit ripple counter which is reconfigured as a shift register to serially output the data from the entire ASIC. Each pixel can be tested individually. Two diverse approaches have been used to prevent coupling between the detector and electronics in MAMBO III and MAMBO IV. MAMBO III is a 3D ASIC, the bottom ASIC consists of diodes which are connected to the top ASIC using μ-bump bonds. The detector is decoupled from the electronics by physically separating them on two tiers and using several metal layers as a shield. MAMBO IV is a monolithic structure which uses a nested well approach to isolate the detector from the electronics. The ASICs are being fabricated using the SOI 0.2μm OKI process, MAMBO III is 3D bonded at T-Micro and MAMBO IV nested well structure was developed in collaboration between OKI and Fermilab.

A photomultiplier (PMT) readout system has been designed for use by the cosmic ray veto systems of two warm liquid bubble chambers built at Fermilab by the Chicagoland Observatory Underground for Particle Physics (COUPP) collaboration. The systems are designed to minimize the infrastructure necessary for installation. Up to five PMTs can be daisy-chained on a single data link using standard Category 5 network cable. The cables is also serve distribute to low voltage power. High voltage is generated locally on each PMT base. Analog and digital signal processing is also performed locally. The PMT base and system controller design and performance measurements are presented.

The simulation results of the timing properties of a plastic scintillator are reported, when it is read by the WLS fiber. For the sake of completeness, we are beforehand with a simplified formula describing the light propagation in a fiber, and thereafter present the simulation results as the distributions for t1-t0 as well as t1+t2 to see the time resolution with t1 and t2 the times appeared at both fiber ends and t0 at the trigger source. The simulations were made for two different WLS fibers, Y11 and BCF92, to see the influence of radiation time on the time resolution.

The existing muon detectors for high-energy physics experiments are mainly made of gas chambers such as Resistive Plate Chambers, Limited Streamer Tubes or Multi Wire Proportional Chambers. With the increasing luminosity of the new accelerators and the increment in dimensions of the experiments the development of a new detection technique, which is robust, cheap and capable to sustain high particle rate, is mandatory. We present the technology proposed for the Super B muon system. The detector is based on MINOS style extruded scintillators coupled to wavelength shifting fibers. The light readout is done by means of Silicon Photomultiplier devices. We report the R&D results on prototypes that can be operated either with binary readout, measuring only one coordinate, or with a TDC readout that can measure both the coordinate at the same time with adequate precision. Efficiency and time resolution will be discussed for different prototype geometry as well as the main operational issues related to the photodetectors, like stability, noise rate and neutron damage. A full-scale prototype with the same geometry designed for the SuperB experiment is under construction in our lab and it will be tested with a muon/pion beam at FNAL next fall. The structure optimization has been studied using a GEANT4 Monte Carlo simulation and the expected muon identification performances have been evaluated with a neural network algorithm, we present preliminary results of the optimization and its implication for the SuperB muon system.

In this work we present the circuit VERDI (VErsatile Readout for Detector Integration), an integrated circuit developed for the readout of different families of radiation detectors, from nitrogen-cooled Ge and Si(Li) detectors, to silicon drift detectors (SDDs), scintillation detectors, photomultipliers tubes and others. The circuit may represent a suitable solution when a compact integration between a multi-element detector and the front-end readout is needed to realize a compact and low-power detection module. The circuit includes 8 channels, each one composed by a charge preamplifier, a shaping amplifier, a gain stage, a baseline holder and a peak stretcher. An on-chip selector provides at the output of each channel the waveform of a specific stage, including an RC integrator for external digital processing of the signal. Alternatively, the 8 channels may be multiplexed on a single output. Different settings, like gain, shaping time, preamplifier compensation and others, may be externally programmed by SPI accordingly to the specific detector in use. Only the input JFET, feedback capacitor and reset device are left external to the ASIC, and must be chosen specifically for each detector. The results of preliminary experimental characterization of the circuit when used with different detectors are presented in this work.

The role of data libraries as a collaborative tool across Monte Carlo codes is discussed. Some new contributions in this domain are presented; they concern a data library of proton and alpha ionization cross sections, the development in progress of a data library of electron ionization cross sections and proposed improvements to the EADL (Evaluated Atomic Data Library), the latter resulting from an extensive data validation process.

Recently, temporal resolution improved prior image constrained compressed sensing (TRI-PICCS), an algorithm promising improved temporal resolution in cardiac CT, was proposed. Here, we extend the ideas to dual source CT. Single source and dual source CT simulations of a heart phantom as well as a single source cardiac CT measurement are used to evaluate the temporal resolution of CT images reconstructed with TRI-PICCS. Short scan reconstructions of the same data are used for comparison. The result of this study is that there seems to be an advantage in temporal resolution when using TRI-PICCS, however, this impression is actually caused by a slight shift of the motion phase when using TRI-PICCS. Comparing short scan reconstructions and TRI-PICCS reconstructions at the same motion phase, no temporal resolution improvement could be confirmed.

Multi-gap Resistive Plate Chamber (MRPC), which has excellent performance and relatively low cost per channel, is a good candidate for Time-of-Flight (TOF) system in modern high energy physics experiments. A new kind of MRPC, Long-strip MRPC (LMRPC) with 50 cm × 2.5 cm strips, was tested at GSI-FOPI with secondary beam. The resets show that this LMRPC prototype can achieve 60 to 70 ps σ time resolution and greater than 97% detecting efficiency. The cross talk between readout strips is less than 2%. The measured spatial resolution along the strips is about 0.36 cm σ.
