Memory of Zbyszko Sosin. Life devoted to physics and the family (1954- 2015)

 

 

"My closer cooperation with Zbyszko Sosin began during my doctoral studies at the Department of Physical Electronics (now the Department of Physics of Hot Matter) of the Institute of Physics of the Jagiellonian University, which was in 1986/87. However, soon I noticed that his area of ​​interest in physics was much broader and also covered the fundamental issues of physics, which he liked to discuss and which he was passionate about: the design of the detectors he had built required not only Excellent knowledge of the physics of collecting charges generated by recorded ions (from alpha particles to very heavy nuclei of about 200 nucleons), but also a unique knowledge of electronics. The spell of inventing and implementing dedicated electronics to the detectors that he built. The result of these activities is the patent, which was obtained together with Eng. Marek Adamczyk on low-noise preamplifier, which is resistant to puncture. I am convinced that many of his original works from the electronics handling particle-loaded electronics could have been patented, but Zbyszek did not pay much attention to documenting his achievements in the field in the form of patents. In fact, the aforementioned preamplifier would probably not have had a patent if it were not for the "light" pressure of the director of the Department of Hot Matter Physics.

He had an analytical mind, extremely analytical. Its typical approach to solving issues related to heavy-ion collision models or the description of charge collecting in silicon detectors after passing a charged particle was to first find an analytical solution for at least part of the problem. Numerical solutions never fascinated him, though, and in this field he was doing great.

Zbyszek was an electronics lecturer for many years who passionately explained to students both the basics and the latest developments. He was an excellent teacher and his relations with the students were excellent. Many students have gone through his "hands", not only to write master or doctoral theses, but also to contribute ideas to them (eg, heart and brain research using nuclear physics).

Zbyszko's interest in science was very broad and it was impossible to mention in this short memo all the issues that interest him. Among his scientific achievements, the development of a model of stochastic nucleon exchange in nucleus-nuclear kinetic energy collisions of up to 100 MeV / nucleon [1], an explanation of the plasma delay effect [2], that occurs during charge collecting in a silicon detector after passing a particle Ionizing, or developing an alpha model of nuclear structure [3], which was the basis of a PhD thesis by Jinesha Kallunkathariyil.

The last detector that was built by Zbyszko is the so-called. Ionisation scintillation detector for detection of alpha particles and fragments of spontaneous fission of super heavy nuclei.

Zbyszek had an excellent sense of humor. He was also a very hospitable person, as I had the opportunity to convince many times (not only me) visiting his house in Lednica Górna (near Wieliczka). It was there I saw that family was very important in his life. I also saw them on our joint trips to experiments with GANIL in France or the Texas A & M University Cyclotron Institute. Coming to the experiment, Zbyszek was already beginning to count the days to return home, which did not bother him at all to work full-time on the experiment and of course to spit out ideas on possible improvements in the detectors we carried with us to these experiments. Zbyszek conducted experiments in many recognized scientific centers. In addition to the previously mentioned were: GSI Darmstadt, KVI Groningen, ILL Grenoble etc.

One of his hobbies to know about us when we were on longer measurements was shopping. Treating it anecdotal, he jokingly commented for Marilyn Monroe, "Money does not bring happiness, it's just buying."

Zbyszko, your work has contributed significantly to the development of the Jagiellonian University, to increase its scientific and didactic potential. The Jagiellonian University has lost a prominent researcher in your field, a specialist in nuclear physics and electronics, a distinguished academic teacher and an educator for many generations of youth.
