It includes a discussion of the JEM-X photon detection sensitivity, the angular resolution, source location accuracy. This presentation focusses on the scientific performance of JEM-X. The detector field of view is constrained by X-ray collimators. The coded masks are located 3.4 m above the detector windows. Each detector has a sensitive area of 500 cm2, and views the sky (5.9 deg FOV, FWHM) through its own coded aperature mask. JEM-X is a coded aperture X-ray telescope consisting of two identical detectors. The unique angular resolution and low energy response of JEM-X will play a crucial role in the detection and identification of gamma ray sources as well as in the analysis and scientific interpretation of the. The INTEGRAL X-ray monitor, JEM-X, (together with the two gamma ray instruments, SPI and IBIS) will provide simultaneous imaging with arcminute angular resolution in the 3-60 keV band. The techniques presented here are useful not only for ICAL, but also for any detector deploying RPCs in large scale. We also suggest a few alternative solutions to improve the time resolution during the operational phase of the INO-ICAL experiment. This technique is validated using an RPC cosmic ray telescope ( ) at TIFR. A new offline correction technique to achieve time resolution below 1 ns, is reported in this paper. The observation of large signals produced by the charged particles passing close to the button spacers also have some repercussion on the overall timing resolution of an RPC. multiplicity as well as lateral position of the trajectory of the charged particle in RPC strip also result in variation of timing information. The position dependent gain is one of the dominant components of the time resolution of a large area single gap RPC. The intrinsic gain of a single gap Resistive Plate Chamber (RPC) is affected by several factors e.g., variation in the thicknesses of glass electrode, button and side spacer, different composition of gas due to improper flow, leaks in the detector volume etc. I will present the detector design and some concerns about bunch growth during the resonant extraction. The effect on beam emittance is minimal, allowing the necessary continuous measurement. This will allow near real-time monitoring of the initial extinction of the beam resonantly extracted from Fermilabs Debuncher before a system of AC dipoles and collimators, which will provide the final extinction. The goal is to verify out-of-bunch extinction to the level 10 in the span of several seconds. Correlating timing information with beam passage will allow the determination of relative beam intensity to arbitrary precision given a sufficiently long integration time. I propose a Cerenkov-based particle telescope to measure secondary production from beam interactions in a several tens of microns thick foil. The out-of-bunch beam must be suppressed by a factor of 10¹° relative to in-bunch beam and continuously monitored. The proposed Mu2e experiment will utilize 200 ns (FW) bunches of 3 x 10 protons at 8 GeV with a bunch-to-bunch period of 1695 ns. For future experiments at the intensity frontier, precise and accurate knowledge of beam time structure will be critical to understanding backgrounds.
