HB 2010 - 46th ICFA Advanced Beam Dynamics Workshop on High-Intensity and High-Brightness Hadron Beams | Year: 2010

Recent status of the high intensity operation of the J-PARC accelerators is presented. Improvements performed in the 2010 summer shutdown period and near future plan are also reported briefly.

The J-PARC main ring synchrotron (MR) has started users operation since 2009. The MR has two beam extraction systems. One is a fast extraction (FX) system for beam delivery to the neutrino beam line of the Tokaito- Kamioka (T2K) experiment, and the other is a slow extraction (SX) system to the hadron experimental hall. For the T2K experiment, the maximum beam power of 145 kW was delivered continuously. For users of the hadron experimental hall, the beam power of 3 kW was delivered with extraction efficiency of 99.5 %. In this paper, status of the high power beam operation of the MR before the Great East Japan Earthquake on March 11, 2011 is presented. Recovery schedule after the earthquake and near future plan are also discussed. Copyright © 2011 by IPAC'11/EPS-AG.

The J-PARC facility was seriously damaged due to the Great East Japan Earthquake on March 11th, 2011. For the Main Ring synchrotron (MR), a few tens of cracks were found in the tunnel and many of them leaked groundwater. Displacements of magnet positions after the earthquake were larger than ±15 mm in horizontal and ±5 mm in vertical. After 9-month recovery work from the earthquake damage, operation of the accelerators was reestablished in late December of 2011. On the other hand, we also made various improvement work to increase the MR beam power during the long shutdown period. In this paper, the recovery work, the improvements and operation status after resuming the user run are presented. Copyright © 2012 by IEEE.

Web venture capital firms may be getting more stringent on the kinds of businesses they invest in, but that doesn’t mean there isn’t still money around for early-stage startups. Index Ventures is carving out a new seed-level fund, Seed Index, from its existing main fund. “First, we are allocating a dedicated pool of capital to do seed deals. We aim to do around 20 seed deals in the next 24 months,” writes Index partner Saul Klein. “Second, we are putting a clearer face and focus on what we do in seed.” Index partners Neil Rimer, Danny Rimer, Klein and Mike Volpi will manage the fund, which is partnering with Klein’s The Accelerator Group; his father Robin is joining as a partner. Since January ’08, Europe’s top tech VC houses have all raised big new funds totaling $2.37 billion through the economy’s downturn…
