Okay, so there hasn’t been an official IceCube press release on this, not until the paper finishes collaboration review and is posted on the Arxiv, but there have been some talks showing neutrino events observed by IceCube which are almost certainly astrophysical in origin. Short version, neutrino astronomy is now a real thing. We are [...]
Multiharmonic rf feedforward system for compensation of beam loading and periodic transient effects in magnetic-alloy cavities of a proton synchrotron
Author(s): Fumihiko Tamura, Chihiro Ohmori, Masanobu Yamamoto, Masahito Yoshii, Alexander Schnase, Masahiro Nomura, Makoto Toda, Taihei Shimada, Katsushi Hasegawa, and Keigo Hara Beam loading compensation is a key for acceleration of a high intensity …
Alternate phase focusing in sequence of independent phased resonators as superconducting linac boosters
Author(s): S. Dechoudhury and Alok Chakrabarti
Theoretical study of an alternate phase focusing (APF) structure, realized in a long chain of double gap quarter wave resonators, capable of accelerating heavy ions from 1.3 to 7 MeV/u has been carried out. Mathieu-Hill stability analysis for the focusing periods consisting of independent resonator…

IceCube probable astrophysical events
Okay, so there hasn’t been an official IceCube press release on this, not until the paper finishes collaboration review and is posted on the Arxiv, but there have been some talks showing neutrino events observed by IceCube which are almost certainly astrophysical in origin. Short version, neutrino astronomy is now a real thing. We are observing the universe in photons (ever since we looked up at the night sky, and starting with Galileo with increasingly sophisticated instruments) and also in neutrinos (which travel undisturbed from deep within the astrophysical objects, reflecting the nuclear interactions deep within).
One of the over 5000 DOMs (Digital Optical Modules) which make up the IceCube Observatory being deployed into the ice.
There’s a nice Gizmodo article with interesting comments.
University of Wisconsin news item.
Phys.org coverage of the news item.
New Scientist entry written by our friend Anil who got to visit IceCube during construction.
Since the middle of last week, the news are spread around and there are Russian, Spanish, and French language versions (at a minimum!) of the news. Previously, only the neutrinos from Supernova 1987A had been seen from beyond the sun and the Earth’s atmosphere. Analysis is still ongoing, so this isn’t a final result by any means, but it is a proof-of-functionality of the IceCube detector and of neutrino astronomy.
Multiharmonic rf feedforward system for compensation of beam loading and periodic transient effects in magnetic-alloy cavities of a proton synchrotron
Author(s): Fumihiko Tamura, Chihiro Ohmori, Masanobu Yamamoto, Masahito Yoshii, Alexander Schnase, Masahiro Nomura, Makoto Toda, Taihei Shimada, Katsushi Hasegawa, and Keigo Hara
Beam loading compensation is a key for acceleration of a high intensity proton beam in the main ring (MR) of the Japan Proton Accelerator Research Complex (J-PARC). Magnetic alloy loaded rf cavities with a Q value of 22 are used to achieve high accelerating voltages without a tuning bias loop. The c...
