The Speedster-EXD- A New Event-Driven Hybrid CMOS X-ray Detector
Christopher V. Griffith, Abraham D. Falcone, Zachary R. Prieskorn +1
The Speedster-EXD is a new 64x64 pixel, 40 m pixel pitch, 100 m depletion depth hybrid CMOS X-ray detector (HCD) with the capability of reading out only those pixels containi…
The speedster-EXD - A new event-triggered hybrid CMOS x-ray detector
Christopher V. Griffith, Abraham D. Falcone, Zachary R. Prieskorn +1
We present preliminary characterization of the Speedster-EXD, a new event driven hybrid CMOS detector (HCD) developed in collaboration with Penn State University and Teledyne Imagi…
Photoelectron track length distributions measured in a negative ion time projection chamber
Z. R. Prieskorn, J. E. Hill, P. E. Kaaret +1
We report photoelectron track length distributions between 3 and 8 keV in gas mixtures of Ne+CO2+CH3NO2 (260:80:10 Torr) and CO2+CH3NO2 (197.5: 15 Torr). The measurements were made…
Characterization of Si Hybrid CMOS Detectors for use in the Soft X-ray Band
Zachary Prieskorn, Christopher V. Griffith, Stephen D. Bongiorno +2
We report on the characterization of four Teledyne Imaging Systems HAWAII Hybrid Si CMOS detectors designed for X-ray detection. Three H1RG detectors were studied along with a spec…
Characterization of an x-ray hybrid CMOS detector with low interpixel capacitive crosstalk
Christopher V. Griffith, Stephen D. Bongiorno, David N. Burrows +2
We present the results of x-ray measurements on a hybrid CMOS detector that uses a H2RG ROIC and a unique bonding structure. The silicon absorber array has a 36μm pixel size, and t…
Burst Fluence Distributions of Soft Gamma Repeaters 1806-20 and 1900+14 in the RXTE PCA era
Zachary Prieskorn, Philip Kaaret
We study the fluence distributions of over 3040 bursts from SGR 1806-20 and over 1963 bursts from SGR 1900+14 using the complete set of observations available from the Rossi X-Ray…
Evidence for 1122 Hz X-Ray Burst Oscillations from the Neutron-Star X-Ray Transient XTE J1739-285
P. Kaaret, Z. Prieskorn, J. J. M. in 't Zand +6
We report on millisecond variability from the X-ray transient XTE J1739-285. We detected six X-ray type I bursts and found evidence for oscillations at 1122 +/- 0.3 Hz in the brigh…
