The Detection of Ionizing Radiation by Plasma Panel Sensors: Cosmic Muons, Ion Beams and Cancer Therapy

The plasma panel sensor is an ionizing photon and particle radiation detector derived from PDP technology with high gain and nanosecond response. Experimental results in detecting cosmic ray muons and beta particles from radioactive sources are described along with applications including high energy and nuclear physics, homeland security and cancer therapeuticsComment: Presented at SID Symposium, June 201

Plasma Panel Sensors for Particle and Beam Detection

The plasma panel sensor (PPS) is an inherently digital, high gain, novel variant of micropattern gas detectors inspired by many operational and fabrication principles common to plasma display panels (PDPs). The PPS is comprised of a dense array of small, plasma discharge, gas cells within a hermetically-sealed glass panel, and is assembled from non-reactive, intrinsically radiation-hard materials such as glass substrates, metal electrodes and mostly inert gas mixtures. We are developing the technology to fabricate these devices with very low mass and small thickness, using gas gaps of at least a few hundred micrometers. Our tests with these devices demonstrate a spatial resolution of about 1 mm. We intend to make PPS devices with much smaller cells and the potential for much finer position resolutions. Our PPS tests also show response times of several nanoseconds. We report here our results in detecting betas, cosmic-ray muons, and our first proton beam tests.Comment: 2012 IEEE NS

Development of a plasma panel radiation detector: recent progress and key issues

A radiation detector based on plasma display panel technology, which is the principal component of plasma television displays is presented. Plasma Panel Sensor (PPS) technology is a variant of micropattern gas radiation detectors. The PPS is conceived as an array of sealed plasma discharge gas cells which can be used for fast response (O(5ns) per pixel), high spatial resolution detection (pixel pitch can be less than 100 micrometer) of ionizing and minimum ionizing particles. The PPS is assembled from non-reactive, intrinsically radiation-hard materials: glass substrates, metal electrodes and inert gas mixtures. We report on the PPS development program, including simulations and design and the first laboratory studies which demonstrate the usage of plasma display panels in measurements of cosmic ray muons, as well as the expansion of experimental results on the detection of betas from radioactive sources.Comment: presented at IEEE NSS 2011 (Barcelona

73.1: Large‐Area Plasma‐Panel Radiation Detectors for Nuclear Medicine Imaging to Homeland Security and the Super Large Hadron Collider

A new radiation sensor derived from plasma panel display technology is introduced. It has the capability to detect ionizing and non‐ionizing radiation over a wide energy range and the potential for use in many applications. The principle of operation is described and some early results presented.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/92058/1/1.3499840.pd

Plasma panel‐based radiation detectors

The plasma panel sensor (PPS) is a gaseous micropattern radiation detector under current development. It has many operational and fabrication principles common to plasma display panels. It comprises a dense matrix of small, gas plasma discharge cells within a hermetically sealed panel. As in plasma display panels, it uses nonreactive, intrinsically radiation‐hard materials such as glass substrates, refractory metal electrodes, and mostly inert gas mixtures. We are developing these devices primarily as thin, low‐mass detectors with gas gaps from a few hundred microns to a few millimeters. The PPS is a high gain, inherently digital device with the potential for fast response times, fine position resolution (<50‐µm RMS) and low cost. In this paper, we report on prototype PPS experimental results in detecting betas, protons, and cosmic muons, and we extrapolate on the PPS potential for applications including the detection of alphas, heavy ions at low‐to‐medium energy, thermal neutrons, and X‐rays.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/98325/1/jsid151.pd

June 1967 in Personal Stories of Palestinians and Israelis

The clash of June 1967, called by Israelis the Six-Day War and by Palestinians the Naksa (setback), is a critical milestone within the longstanding Israeli- Palestinian conflict. Despite all the scholarly attention ever since, there remain unheard voices and untold stories. It is the personal stories of people in the region that are at the center of this book. How do they remember 1967? How were their lives affected, even changed dramatically as a result of that short war? Listening to their stories as told some 50 years later, an incomplete tapestry of memories and understandings emerge. This book is the product of a re- search collaboration among Palestinian, Israeli and European folklorists, cultural anthropologists and sociologists. The personal stories were collected in the framework of interviews with men and women from all walks of life, on the days before, during and after this dramatic confrontation. The book is comprised of eleven chapters based on a corpus of several hundred conversations, as well as eight representative interviews. Together they afford insight into differential memories and sensations, visions of euphoria and despair, newly revived hopes, pain and disappointment, disillusionment and repentance
