• First beam extracted to the Hadron Hall and the "First-Beam Workshop at the J-PARC Hadron Experimental Hall"
  As was announced by a press release, that was also informed by a Special Issue of the Newsletter, the first proton beam was successfully accelerated to 30 GeV in the 50-GeV synchrotron (MR), extracted, and transported to the beam dump of the Hadron@Hall on January 27th. On that day, both the accelerator and the hadron teams started an attempt to slow-extract a proton beam for the first time, and only after a few hours of the effort, a proton beam was successfully observed at the beam dump with a monitor at 19:35. After a scheduled maintenance of the accelerator, on February 10th, the production target, T1, was inserted into the proton beam to produce secondary beams. The first secondary beam was observed by the E15/E17 experiment team, headed by Prof. Ryugo Hayano (Tokyo) and Prof. Masahiko Iwasaki (RIKEN), at the K1.8BR beamline.
  
  The "First-Beam Workshop at the J-PARC Hadron Experimental Hall" was held at the Ibaraki Quantum Beam Research Center, located just in front of the J-PARC site, on March 25th and 26th. About 100 researchers attended the meeting. They discussed reports on the first beam from the accelerator team, the hadron beamline team, and the E15/E17 team, as well as the reports by the experimental groups who expect to use the beams in this fall at the K1.8 beamline and the KL beamline. In addition, they were encouraged by the talks from noted theorists, Prof. Tetsuo Hatsuda and Prof. Yasuhiro Okada, hearing physics opportunities in the Hadron Hall. In the afternoon of March 26th, a tour to the Hadron Hall and a general assembly of the Hadron Hall Users Association (HUA) also took place.
  
  We are very much excited on the beginning of the new era with the Hadron Hall.

• The construction of the J-PARC Hadron Hall was finished at the end of June 2007, and an excursion to introduce the newly completed Hadron Hall was held on Friday, July 27, from 1:30pm to 4:30pm. The participants numbered about 250 and included staff from KEK, JAEA, affiliate companies involved in the construction, and participating universities and institutes. Members of the mass media, such as NHK, were also present to gather information about the Hadron Hall. Beginning at 2:30pm, addresses were delivered by Prof. Shoji Nagamiya (head of the J-PARC Center), Prof. Fumihiko Takasaki (head of the KEK IPNS), Prof. Kazuma Nakazawa (chair of the Hadron Hall Users' Association and a professor at Gifu University), and Toshio Tanaka (head of the facilities department at KEK). Next, J-PARC staff talked about the T1 target (secondary target), the beam dump, the K1.8 and K1.1 beamlines, and the switching yard. Finally, the users described the experiments to be prepared at each beamline. The Hadron Hall beamlines will be installed and the experimental apparatus prepared in time for the first proton beam in December 2008.
