We developed a front-end ASIC for future PET scanners with time-of-flight (TOF)
capability to be coupled with 4×4 Multi Pixel Photon Counter (MPPC) arrays.
The ASIC is designed based on the open-IP project proposed by JAXA and realized in
TSMC 0.35 μm CMOS technology. The circuit comprises 16-channel, low impedance
current conveyers to effectively acquire fast MPPC signals. For precise...

This paper presents how a large area thin film transistor (TFT) x-ray imaging sensor has been applied to calibrate the gantry geometry and acquire x-ray projection images in cone-beam computed tomography (CBCT) system. A cone-beam x-ray tube and TFT imaging sensor could enable imaging of entire organ in one axial acquisition using one rotation of the gantry. The gantry motion could measure,...

We are working on the proposed "BeamCal" project. Its goal is to detect scattered incoming beams at ILC at small angles, to prevent the background from two-photon processes to mimic signatures of new discoveries. The detector, which is envisioned as a tungsten sandwich calorimeter, will be subject to high fluences EM radiation that will shower in the tungsten radiator. We are exploring the...

The byte-wide optical link in the CDF Run II silicon tracking system has endured a decade of operation and delivered an integrated luminosity of 12 fb-1. The modules consist of a transmitter converting detector signals to optical pulses, connected with 22 m fiber ribbon cables carrying signals to receiver modules out of the detector. The data transmission is conducted with edge-emitting type...

It is foreseen to significantly increase the luminosity of the LHC by upgrading towards the HL-LHC (High Luminosity LHC) in order to harvest the maximum physics potential. Especially the Phase-II-Upgrade foreseen for 2021 will mean unprecedented radiation levels. All-silicon central trackers are being studied in ATLAS, CMS and LHCb, with extremely radiation hard silicon sensors to be employed...

AC-coupled silicon strip sensors can get damaged in case of a beam loss due to the possibility of a large charge accumulation in the bulk, developing very high voltages across the coupling capacitors which can destroy them [1]. Punch-through protection (PTP) structures are currently used to avoid this problem helping to evacuate the accumulated charge as large voltages are developing [2]....

First prototype of the new 3D-Stripixel Detectors has been fabricated by CNM of Spain. TCT test results using lasers of various wavelengths (660 to 1.06um) have shown good 2D-position sensitivity with one-sided processing. CCE test by ALIBAVA using the laser with um-beam size have shown sub-pixel (80 um)2D position resolution. Recent BNL ALIBAVA tests using a 1.06 um laser with mm-beam size...

In recent years, digital mammography with advantages of high sensitivity to low-contrast masses, wider dynamic range and lower radiation dose has been introduced as a new alternative to conventional X-ray film-screen mammography. At the present time, both indirect X-ray conversion approach using a combination of a-Si:H with thin film transistors(TFT), CCD(Charge coupled device) and suitable...

We report on the recent development of a 64-channel analog front-end ASIC for a new gamma-ray imaging system to visualize radioactive substances. The imaging system employs a novel Compton camera which consists of silicon and cadmium telluride (CdTe) detectors. The ASIC aims for the readout of pixel /pad detectors utilizing Si/CdTe as detector materials, and the dynamic range from 100 keV to...

Various structures for n-in-p planar pixel sensors have been developed at KEK in order to cope with the huge particle fluence in the upcoming LHC upgrades.
Performances of the sensors with the different structures have been evaluated with testbeam.
The n-in-p devices were connected by bump-bonding to the ATLAS Pixel front-end chip (FE-I4A) and characterized before and after the irradiation...

We have fabricated n-in-p miniature silicon microstrip sensors and small test structures. A p-stop structure is implemented in order to isolate the n-implant against the inversion layer of electrons in the interface of silicon bulk and the oxide surface passivation. Along irradiation the strongest electric field is said to move from the edge of the n-implant to the edge of the p-stop due to...

In view of the LHC upgrade phases towards the High Luminosity LHC (HL-LHC), the ATLAS experiment plans to upgrade the Inner Detector with an all-silicon system. Because of its radiation hardness and cost effectiveness, the n-on-p silicon technology is a promising candidate for a large area pixel detector.
