Compact sub-10 ps Resolution Radio Frequency Photomultiplier Tube
Sergey Abrahamyan, Simon Zhamkochyan, Hasmik Rostomyan +16
Experimental measurements of the radial spreading of photoelectrons emitted from a multi-alkali photocathode in a MCP-based photomultiplier tube have shown that, for photon wavelen…
A Helical-Deflector-Based Radio-Frequency Spiral Scanning System for keV Energy Electrons
Simon Zhamkochyan, Vanik Kakoyan, Vardan Bardakhchyan +21
We present the design, modeling, and experimental validation of a radio-frequency based time-to-position conversion system for keV electrons incorporating a helical deflector opera…
Precise measurement of the -binding energy difference between H and H via decay-pion spectroscopy at MAMI
Ryoko Kino, Sho Nagao, Patrick Achenbach +31
We performed high-precision decay-pion spectroscopy of light hypernuclei at the Mainz Microtron (MAMI) using the A1 spectrometer facility. By measuring the monochromatic …
Picosecond Precision Heavy-Ion Detector for Λ Hypernuclei Lifetime Studies
Simon Zhamkochyan, Sergey Abrahamyan, Amur Margaryan +18
In this paper, we present the design and preliminary performance evaluation of a new heavy-ion detector for direct measurements of heavy Λ hypernuclei lifetime. The detector employ…
Picosecond resolution photoelectron emission lifetime detection system
V. Kakoyan, S. Zhamkochyan, S. Abrahamyan +21
This paper describes a new photoelectron emission lifetime detection system. It is based on a recently developed Radio Frequency Timing technique of keV electrons and a 40 MHz, ult…
Measurement of the Ar(e,e) elastic scattering cross section with a novel gas-jet target
M. Littich, L. Doria, P. Brand +35
We report on a measurement of elastic electron scattering on argon performed with a novel cryogenic gas-jet target at the Mainz Microtron accelerator MAMI. The luminosity is estima…
