Abstract We present the research and development work of first version a 6×6 array silicon pad detectors, carried out in India, for proposed forward calorimeter (FOCAL) as part ALICE collaboration upgrade program at CERN. The primary motivation is to develop large area realizing challenging requirements high-energy physics experiments such low leakage current, high breakdown voltage evaluate it...

This paper presents the principles of operation Resistive AC-Coupled Silicon Detectors (RSDs) and measurements temporal spatial resolutions using a combined analysis laser beam test data. RSDs are new type n-in-p silicon sensor based on Low-Gain Avalanche Diode (LGAD) technology, where $n^+$ implant has been designed to be resistive, read-out is obtained via AC-coupling. The truly innovative fe...

We developed a compact tactile sensor in order to guide the clinician or the self-user for non-invasive detection of lumps. The new design has an advantage over the existing discrete tactile sensors and detection methods by efficiently sensing force distribution over an area without any side effects. The sensor consists of 10×10 infrared emitter-detector pairs, a silicon-rubber elastic pad, and...

In the context of particle detectors, low-temperature covalent wafer-wafer bonding allows for integration high-Z materials as absorbing layers with readout chips produced in standard CMOS processes. This enables instance fabrication novel highly efficient X-ray imaging sensors. order to investigate effects on signal generated such sensors, bonded silicon-silicon P-N pad diodes have previously b...

We present an implantable sub-micron silicon probe device, with flexible interconnects, that is capable of intracellular neuronal recording. The silicon probe device’s ability to penetrate and record from neurons in an isolated brain of the sea slug Tritonia diomedea was tested, and we demonstrate that, for the first time, an implantable device can record intracellular action potentials from a ...

Abstract A tabletop Two Photon Absorption-Transient Current Technique (TPA-TCT) set-up built at CERN was used to investigate a non-irradiated PIN diode, an irradiated and 5 × 5-multipad HPK LGAD. The intrinsic three dimensional spatial resolution of this method is demonstrated under normal incidence the laser probe. charge collection versus depth profile diode presented, where reflection on rea...

The main objective of this research is to develop a micro and nanogap structure using dry anisotropic etching –Reactive Ion EtchingRIE. Amorphous silicon material is used in the micro and nanogap structure and gold as electrode. The fabrication processes of the micro and nanostructure are based on conventional photolithography, wet etching for the Al pattern and wet etching for a-Si pattern usi...

We have designed, fabricated, and characterized two-dimensional 16x16-element capacitive micromachined ultrasonic transducer (CMUT) arrays. The CMUT array elements have a 250-μm pitch, and when tested in immersion, have a 5-MHz center frequency and 99% fractional bandwidth. The fabrication process is based on standard silicon micromachining techniques and therefore has the advantages of high yi...

We report a novel approach for on-chip electrical detection of the radiation guided by dielectric-loaded surface plasmon polariton waveguides (DLSPPW) and DLSPPW-based components. The detection is realized by fabricating DLSPPW components on the surface of a gold (Au) pad supported by a silicon (Si) substrate supplied with aluminum pads facilitating electrical connections, with the gold pad bei...
