Su‐E‐J‐66: Evaluation Of Proton Induced X‐Ray Fluorescence From Gold Fiducial Markers For In‐Vivo Determination Of Proton Range And Energy

Abstract

A polymer-stabilized blue-phase liquid crystal (BPLC) with microsecond response time is demonstrated using a vertical field switching cell. The measured decay time is 39.4 μs at room temperature (21°C) and then decreases to 9.6 μs at 44.3 °C. Such a response time is 1-2 orders of magnitude faster than that of a typical BPLC device. The responsible physical mechanisms are the collective effects of short pitch length, strong polymer network, and low viscosity through elevated temperature effect. The on-state voltage of our BPLC device is 44.2 V, hysteresis is below 0.7%, and contrast ratio is over 1300:1.
