The Polish synchrotron radiation facility, Solaris, is being built in Krakow. The project is strongly linked to the MAX-IV project and the 1.5 GeV storage ring. An overview will be given of activities and of the control system and will outline the similarities and differences between the two machines.

in Undetermined The Polish synchrotron radiation facility Solaris is being built at the Jagiellonian University in Krakow. The project is based on an identical copy of the 1.5 GeV storage ring being concurrently built for the MAX IV project in Lund, Sweden. A general description of the facility is given together with a status of activities. Unique features associated with Solaris are outlined, such as infrastructure, the injector and operational characteristics.

Solaris is a third generation light source recently constructed at the Jagiellonian University in Krakow. The installation of the 600 MeV S-band linear accelerator with thermionic RF gun and transfer line as well as the 1.5 GeV storage ring is now complete. In November 2014 subsystem tests and conditioning of the Solaris linac were started. A 300 MeV electron beam at the end of the linac was observed for the first time in February 2015 after which the machine was shut down for 2.5 months to complete transfer line and storage ring installation. In May the commissioning of the linac together with the transfer line and storage ring began. The beam was soon observed on the YAG screen monitor, installed at the injection straight in the storage ring. The beam current measured with the fast current transformer in the transfer line was 8 mA over 180 ns, at 360 MeV. The commissioning of the machine is still in progress and preliminary results of Solaris are presented.

Solaris, a 1.5 GeV third generation synchrotron light source, was commissioned in 2016 April and is currently operated in decay mode. Two beamlines PEEM/XAS and UARPES were installed and now are being commissioned. Three more PHELIX, XMCD and diagnostic beamlines have received funding and will be installed and commissioned in next few years. With total accumulated beam dose near to 690 A.h and three orders of magnitude reduction of outgassing the design goal of 500 mA beam current and electron energy of 1.5 GeV has been achieved. As the beam current was increased, a few vacuum problems were encountered, including vacuum leaks in RF and arc sectors and unexpected pressure bursts near photon absorbers. Lessons learned and operational experience will be presented and discussed in this paper. ACCELERATORS VACUUM SYSTEM The Solaris light source is based on a 0.6 GeV S-band linac with a thermionic RF gun, a vertical dog-leg transfer line and a 1.5 GeV storage ring with 96 m circumference....

Radiation measurements at Solaris are continuously performed by using 9 radiation monitor stations (RMS) located around the storage ring and the beamlines area. 4 of RMS are connected to the Personal Safety System and in case of exceeding alarm level dump the beam or close safety shutters. Moreover thermoluminescence dosimeters (TLDs) are used to registered doses in the classified areas according to the Polish regulation. Measurements are performed since 2015 when the commissioning of the storage ring has started. Since that time several improvements to the radiation shielding was done to fulfill the ALARA principle. Moreover the electron beam optimizations during the injection, ramping and operation were performed to decrease the electrons losses and the radiation level. This presentation will report on radiation measurements results obtained before and after the chopper installation. Additionally problems with radiation level while the beam current is increasing to the designed 50...

Register here: https://www.ijss.org!! Join us for a day of reflection and study in memory of our dear friend and colleague Rabbi Ellen Bernstein, a trailblazing educator, a thoughtful scholar, and a pioneer in the field of religious environmental work. This virtual summit provides an opportunity to explore a set of interwoven themes connected to questions of spiritual ecology. Bridging between ancient wisdom and present crisis, our panelists will speak about the religious values, ideas, and traditions that continue to inform and animate their ecological work and social activism. Theology: Our first panel will discuss what it means to read scripture or sacred text in this time of pressing ecological and looming environmental disaster. They will grapple with the question of how we might “do” theology in our day, considering how religious narratives can help us construct a better future. Contemplation: The second session will highlight the power of contemplative ecology, examining how the practices of coming to attention can help us build spiritual sensitivity to see the world with new eyes while stretching our moral imagination. Education and Activism: Our third and final panel will be devoted to exploring the relationship between scholarship, spiritual education, and activism. Approaching study and application as essentially intertwined, our speakers will share their experiences as teachers and practitioners both in the classroom and in the field.

The text deals with the current topic of the sixteenth regular assembly of the Synod of Bishops of the Catholic Church, the first phase of which includes not only the active participation of all Catholic faithful, but is also open to Christians of other churches. The text first shows that the invitation addressed to non-Catholics to participate in the synodal process is based on the ecclesiological foundations established by the Second Vatican Council. In the second part, the article places the synodal process within the framework of Pope Francis' reform efforts, which includes the missionary renewal of the Church and have its important ecumenical impact. The third part deals with the analysis of the character of the synodal process in terms of ecumenical hermeneutics, focusing on its pastoral and spiritual dimension.
The Oppenheimer biopic seems to have been quite a success. Except in Japan, where he didn't finish making the weight. The origin of the rejection was the film's treatment of a key point-tiptoeing over it, ignoring it, or almost-in the story. The practical assay on the cities of Hiroshima and Nagasaki of the outcome of the Manhattan Project: the explosion of the first two nuclear fission bombs. In this recent movie, we see how the bombs, supposedly already finished and ready to be used to roast, grind, evaporate, ... are taken out of the New Mexico desert complex in military trucks. Without the project manager being able to say a word. The test at Álamo Gordo was previously being seen in the film. The first atomic blast forced Humanity into a new era. No one of us was able to say much about it either.
