“…The spatial temperature distribution from the electrical contact at the edge of MCP outward to the exposed area of the MCP was modeled by Matsuura et al [] for various MCP resistances. A 10 MΩ MCP with 1000 V applied was calculated to be ~20 C higher in the exposed area than at the edge clamp.…”

Microchannel plates (MCPs) have been used for many years in space flight instrumentation as fast, lightweight electron multipliers. A new MCP fabrication method combines a glass substrate composed of hollow glass capillary arrays with thin film coatings to provide the resistive and secondary electron emissive properties. Using this technique, the gain, resistance, and glass properties may be chosen independently. Large‐area MCPs are available at moderate cost. Secondary emission films of Al2O3 and MgO provide sustained high gain as charge is extracted from the MCP. Long lifetimes are possible, and a total extracted charge of 7 C/cm2 has been demonstrated. Background rates are low because the glass substrate has little radioactive potassium 40. Curved MCPs are easily fabricated with this technique to suit instrument symmetries, simplifying secondary electron steering and smoothing azimuthal efficiency.

“…The saturation of MCP gain is a well-known phenomena, and the most dominant mechanism is attributed to the accumulation of space charges due to uncanceled electron current toward the output end of the capillaries. 22) Kikuchi et al reported a calibration method for the saturation of the MCP gain. 19) According to their report, the secondary electron amplification gain G is divided into two parts as…”

Methods for calculating multiple point T, relaxation images are described and compared. A robust line fitting method is presented and its relevance to high resolution relaxation imaging discussed. Selective removal of data points is demonstrated to reduce systematic errors in linear models.A non-linear least squares iterative method is also developed and implemented. The results include simulated data, clinical images and a phantom study. Several of the methods are substantial improvements on existing linear techniques. The increased quality and consistency of the calculated images make them particularly appropriate for automated pattern recognition.

“…While the MCP has a very high sensitivity, its gain starts to degrade once the output current exceeds 5 -10% of the strip current. [55][56][57][58] The magnitude of an output signal is then not proportional to the total number of incident ions. The MCP is, therefore, suitable for measuring thin plasmas.…”

A tabletop experimental system has been developed for the study of various collective effects in space-charge-dominated beams. It is based on the recently proposed idea that the dynamic motion of a one-component plasma in a trap can be made physically equivalent to that of a charged-particle beam propagating through a linear transport channel. In this paper, we report on the details of the system and on results of test experiments with a compact Paul trap that is divided into several independent sections. The trap design is carried out in consideration of practical constraints. A Maxwell equation solver is used to calculate the properties of the plasma confinement potential. Experimental observations are compared with numerical data obtained by a tracking simulation code that enables us to approximately predict the three-dimensional trajectories of particles in the system. Low-density N 2 þ plasmas are employed to examine the basic performance of the multi-section trap. The initial temperature, density and lifetime of a confined plasma are estimated from experiments and simulations.
