Particle Identification at VAMOS++ with Machine Learning Techniques
Y. Cho, Y. H. Kim, S. Choi +45
Multi-nucleon transfer reaction between 136Xe beam and 198Pt target was performed using the VAMOS++ spectrometer at GANIL to study the structure of n-rich nuclei around N=126. Unam…
Design report of the KISS-II facility for exploring the origin of uranium
Takamichi Aoki, Yoshikazu Hirayama, Hironobu Ishiyama +14
One of the critical longstanding issues in nuclear physics is the origin of the heavy elements such as platinum and uranium. The r-process hypothesis is generally supported as the…
The new MRTOF mass spectrograph following the ZeroDegree spectrometer at RIKEN's RIBF facility
M. Rosenbusch, M. Wada, S. Chen +23
A newly assembled multi-reflection time-of-flight mass spectrograph (MRTOF-MS) at RIKEN's RIBF facility became operational for the first time in spring 2020; further modifications…
Reduction of contaminants originating from primary beam by improving the beam stoppers in GARIS-II
Sota Kimura, Daiya Kaji, Yuta Ito +4
Two independent beam stoppers have been developed for improving the beam separation of the gas-filled recoil ion separator GARIS-II. Performance evaluation of these supplemental be…
Accurately accounting for effects on times-of-flight caused by finite field-transition times during the ejection of ions from a storage trap: A study for TOF and MRTOF mass spectrometry
M. Rosenbusch, P. Schury, M. Wada +3
In applied forms of time-of-flight mass spectrometry utilizing ion storage devices prior to an analysis device, a non instantaneous electric ejection pulse applied in the region of…
An inexpensive biasing system for use in electrostatic steering of ions
P. Schury
We introduce a compact design for an electronic device capable of superposing 8 bias voltages up to 96~V on a voltage of up to 5~kV. Such a device has been implemented to prov…
High-stability, high-voltage power supplies for use with multi-reflection time-of-flight mass spectrographs
P. Schury, M. Wada, H. Wollnik J-Y. Moon +2
Achieving the highest possible mass resolving power in a multi-reflection time-of-flight mass spectrometer requires very high-stability power supplies. To this end, we have develop…
Improving wide-band mass measurements in a multi-reflection time-of-flight mass spectrograph by usage of a concomitant measurement scheme
P. Schury, Y. Ito, M. Rosenbusch +3
We introduce a new concomitant referencing mode for operating a multi-reflection time-of-flight mass spectrograph (MRTOF-MS), wherein the reference and analyte ions are interleaved…
A novel ion cooling trap for multi-reflection time-of-flight mass spectrograph
Y. Ito, P. Schury, M. Wada +8
A radiofrequency quadrupole ion trap system for use with a multi-reflection time-of-flight mass spectrograph (MRTOF) for short-lived nuclei has been developed. The trap system cons…
Development of a resonant laser ionization gas cell for high-energy, short-lived nuclei
T. Sonoda, M. Wada, H. Tomita +21
A new laser ion source configuration based on resonant photoionization in a gas cell has been developed at RIBF RIKEN. This system is intended for the future PArasitic RI-beam prod…
