any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...

This paper describes an intercepting beam intenSity profile and position monitor which was developed at SLAC. It has excellent spatial resolution as well as signal efficiency. The instrument utilizes the electromagnetic cascade shower emission effect. Net charge leakage signals comparable in magnitude to the intercepted beam current are easily obtainable. The latest model of the instrument is d...

The stability of delivery of low monitor unit (MU) setting is important especially for step-andshoot intensity-modulated radiotherapy (IMRT), because the nature of the technique is inherent to repeat beam on/off according to the number of the segments. This study evaluates the dose linearity and profile flatness/symmetry under low MU settings for Vero4DRT, a new linear-accelerator based irradia...

Abstract The intraday trades profile is the expected intensity of a counting process where counts measure number over an interval. It needs to capture salient features trading activity, its spikes, and periods relative quietness. This calls for estimator with time varying resolution that allows us identify jumps. problem can be recast as regression one, using fused Lasso penalty. framework jump...
