Bent Herskind, one of the pioneers of the experimental high-spin nuclear physics, passed away on December 7, 2021, in the age of 90.

Bent Herskind was born in 1931 in Copenhagen. He was employed from 1956 at the Niels Bohr Institute (NBI), Copenhagen, first as Research Assistant, developing electronics for nuclear research first at the NBI Van de Graff and later at the Tandem Accelerator Laboratory (TAL). He was called to a Research Associate Position in 1966 at NBITAL and had a leave of absence to University of Wisconsin, Madison for 18 month (1966-67). He was appointed associate professor at NBI in 1971, and received the Ph.D. in physics in 1974. He was editor of the journals, Hyperfine Interaction, North Holland (1976-82), Zeitschrift für Physik A: Hadrons and Nuclei (1985-95) and The European Physics Journal, A. (1995-97). He acted as Scientific Consultant at Lawrence Berkeley Laboratory, US, with 2 months/year visits (1980-85), and was visiting professor at the Atomic Energy Commission Laboratories , Chalk River, Canada (1975) and at Oak Ridge National Laboratories, Tennessee, US, in 1982 and 1987. Initiated together with professor Peter Twin the development of the germanium multi-detector Escape Suppression Array, TESSA0 at NBITAL (1980-82); which was upgraded to TESSA1-3 and ESSA30 at Daresbury, UK (1982-88); later NORDBALL was developed at NBITAL (1985-98). Finally, the European project, EUROBALL (EB) were build. He was Chairman of the EB Steering Committee during 4 years (1989-92 and 1997), and for the EB Data Analysis Group (1993-96). He received Philosophiae Doctorem Honoris Causa, at The University of Lund in 1990. He retired from the official position at NBI, University of Copenhagen in Jan. 2002, but continued the nuclear structure research at NBI, full time. His research interests were very broad, from Transient Magnetic Fields, Giant Dipole Resonance in Hot Nuclei, Rotational and Compound Damping in Warm Nuclei, up to his main latest activity of the Complete Spectroscopy of Super- and Hyper-deformation.  His was the co-author of more than 400 scientific publications.

He was collaborating closely with many Polish physicist from Krakow and Warsaw, and he was participating in many conferences organized in Poland.

The Faculty of Physics and the Faculty of Management at the University of Warsaw invite you to a seminar under the patronage of the Minister of Climate and Environment entitled
“Current challenges related to the implementation of the Polish Nuclear Power Program” (in Polish).
The seminar will be held on November 29, 2021 at 9:00 online.

The seminar will be held remotely via the videoconference platform. Anyone who completes the registration form will receive a link to the platform and will be able to actively participate in the seminar by asking questions to the speakers.
Additionally, during registration, it is possible to ask a question to all or a selected Participant of the discussion panel. Please enter your question in the registration form with the information to whom it is addressed. Note – due to the limited time of the discussion panel, only a few, the most interesting questions will be selected.

The next Physical Seminar of OK Polish Physics Society will be held on the 25^th of November 2021 at 16:15, online on the MS TEAMS platform.

Dr hab. Renata Kopeć, Prof. IFJ (H. Niewodniczański Institute of Nuclear Physics PAS) will present:

“Five years of proton radiotherapy with the use of a pencil scanning beam at the Cyclotron Center Bronowice IFJ PAN”,

Prof. Marek Jeżabek (The H. Niewodniczański Institute of Nuclear Physics of the Polish Academy of Sciences) will deliver a lecture:

“How the CCB was built.”

Summary:
1. The Bronowice Cyclotron Center has two gantry stations where it is possible to use a scanning proton beam for cancer radiotherapy. Proton radiotherapy with the use of a pencil scanning beam is currently one of the most advanced and precise radiotherapeutic techniques using ionizing radiation. Its main advantage is the ability to precisely deliver high doses of radiation to neoplastic lesions while saving healthy tissues. On the 3sup>rd of November 2021, 5 years have passed since the start of proton radiotherapy with the use of a pencil scanning beam on gantry stations at the Bronowice Cyclotron Center at the Institute of Nuclear Physics of the Polish Academy of Sciences.
2. Memories from the years 2004 – 2016 and a few remarks about proton radiotherapy in Poland.

We suggest that people who did not use the MS TEAMS platform install the MS TEAMS application beforehand.
