Autor: Gerald J. Diebold, Bernhard W. Adams, Christoph Rose-Petruck, Pawel Chmielniak, Michael Michon, Tomáš Parkman, Keith Bisogno, Daniel DeCiccio

Publikováno v: Advances in X-Ray/EUV Optics and Components XVI.

A Laser-Driven Plasma X-ray Source (LPXS) can provide intense, hard X-rays in femtosecond pulses emitted from a micrometer-size spot on a recirculating liquid-metal target. Unlike X-ray tubes based on electron beams, which are subject to constraints

From optical to X-ray ghost imaging

Autor: Bernhard W. Adams, Thomas A. Smith, Lei Xia, Yanhua Shih, Robert Wagner, Xuan Li, Zhehui Wang, Chen Hu, Liyuan Zhang, Ren-Yuan Zhu, Marcel Demarteau, Junqi Xie

Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 935:173-177

Recent advances in ghost imaging techniques and X-ray sources such as synchrotrons and, more recently, X-ray free-electron lasers (XFEL) have made X-ray ghost imaging a growing topic of interest. One specific type of ghost imaging utilizes thermal ra

First experimental demonstration of time-resolved X-ray measurements with next-generation fast-timing MCP-PMT

Autor: Chen Hu, John P. Katsoudas, Yujia Ding, Bernhard W. Adams, Lei Xia, Marcel Demarteau, Junqi Xie, Yanhua Shih, Xuan Li, Robert Wagner, Zhehui Wang, Liyuan Zhang, Thomas A. Smith, Ren-Yuan Zhu

Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 927:287-292

We report the first successful time-resolved X-ray measurements at the APS 10-ID-B beamline by coupling ultrafast scintillators with photodetectors. Multiple scintillator and sensor pairs (LYSO, plastic scintillator, dynode PMTs, MCP-PMT), as well as

Low-Dose High-Resolution TOF-PET Using Ionization-activated Multi-State Low-Z Detector Media

Autor: K. Domurat-Sousa, Bernhard W. Adams, A.H. Squires, E. Spieglan, Evan Angelico, J.F. Shida, P.J. La Riviere, Henry J. Frisch, A. Elagin

Publikováno v: Nucl Instrum Methods Phys Res A

We propose PET scanners using low atomic number media that undergo a persistent local change of state along the paths of the Compton recoil electrons. Measurement of the individual scattering locations and angles, deposited energies, and recoil elect

Air-transfer production method for large-area picosecond photodetectors

Autor: Henry J. Frisch, Evan Angelico, A. Elagin, E. Spieglan, M. R. Foley, Bernhard W. Adams, Michael J. Minot

Publikováno v: The Review of scientific instruments. 91(5)

We have designed and prototyped the process steps for the batch production of large-area micro-channel-plate photomultipliers (MCP-PMT) using the "air-transfer" assembly process developed with single $LAPPD^{\text{TM}}$ modules. Results are presented
