A Study of Three Dimensional Edge and Corner Problems using the neBEM Solver
Supratik Mukhopadhyay, Nayana Majumdar
The previously reported neBEM solver has been used to solve electrostatic problems having three-dimensional edges and corners in the physical domain. Both rectangular and triangula…
Fast and Precise 3D Computation of Capacitance of Parallel Narrow Beam MEMS Structures
N. Majumdar, S. Mukhopadhyay
Efficient design and performance of electrically actuated MEMS devices necessitate accurate estimation of electrostatic forces on the MEMS structures. This in turn requires thoroug…
3D Simulation of New Generation Gas Detectors
S. Mukhopadhyay, N. Majumdar
Simulation of new generation gas detectors is rendered complicated due to the non-trivial nature of the electric field and simultaneous presence of several length-scales. Computati…
Estimation of Weighting Potential for a TPC
S. Mukhopadhyay, N. Majumdar, R. Veenhof
In this work, we have computed the three dimensional weighting potential, field and pad response function (PRF) of typical time projection chambers (TPC) using a recently formulate…
Simulation of Pickup Signal in a Resistive Plate Chamber
N. Majumdar, S. Mukhopadhyay, S. Bhattacharya
The signal induced by an electron on a pickup strip has been calculated in a RPC used in INO calorimeter following Ramo's theorem. An accurate estimation of weighting field has bee…
Computation of Electrostatic and Gravitational Sag in MultiWire Chambers
N. Majumdar, S. Mukhopadhyay
A numerical method of determining the wire sag in a multiwire proportional chamber used in RICH (ALICE) by solving the second order differential equation which governs the wire sta…
