CARE-HHH Network: Annual Report 2007

W. Scandale, and F. Zimmermann, 5 December 2007

In 2007 the networking activity of CARE-HHH continued to focus on the high-luminosity upgrade of the LHC at CERN, the upgrade of the LHC injector complex, and the FAIR project at GSI.

Triggered by the results of the HHH studies obtained since 2004, in 2007 several new working groups were launched inside CERN, dedicated to the design of a PS successor “PS2”, to the enhancement of the SPS, and to the upgrade of the LHC interaction regions, respectively. In parallel, the development of magnet prototypes for the LHC interaction region upgrade was approved as a new infrastructure initiative (CNI) within the European Union’s 7th framework programme. In terms of budget and resources, these greatly expanded studies go far beyond HHH.

In 2007, two main upgrade paths for the LHC, identified at the CARE-HHH-APD LUMI’06 workshop, were confirmed and further elaborated, namely the early separation (ES) scheme, and the large-Piwinski angle (LPA) scheme. The average luminosity reach of either scheme as a function of the IP beta function was computed, demonstrating that the ES option in its original form requires more focusing to be competitive. Various options for luminosity leveling in both approaches were explored. Small-angle crab cavities for the LHC upgrade have received renewed interest, either as a component of the early-separation scheme or as a standalone alternative.

Networking aspects: Major HHH workshops in 2007 (BEAM’07, IR’07, THERMOMAG) were organized to complement the greatly expanded CERN studies on the LHC and LHC injector upgrade by reinforcing contacts with, and providing input and help from, the European partner institutes and the international community, in particular US-LARP. A dedicated HHH mini-workshop on electron-cloud countermeasures, “ECL2”, gave birth to three new electron-cloud suppression schemes and led to the launch of a concrete and active improvement programme for the SPS.

Two specific HHH working groups created in 2005 continued to be active in 2007. The first, addressing issues such as accelerator physics and machine-detector interface aspects related to the upgrade of the LHC Interaction Regions, took a closer look at magnetic elements integrated into the detectors. The second was investigating an appropriate R&D programme for AC superconducting magnets in view of the upgrade of the LHC injector complex and of FAIR at GSI and it developed preliminary super-ferric magnet designs, as a starting point for future optimization.

A networking support to crystal channeling, reflection and collimation began at the end of 2005 and continued all along 2006 and 2007, providing a forum of discussion to which many associated institutes in Russia and US, such as IHEP, PNPI, JINR and FNAL, could contribute. Several mini-workshops on crystal collimation were organized within this activity. Support was provided for the completion of a master thesis. In 2007 HHH also supported participation in beam experiments with crystals at the SPS and the FNAL Tevatron, as well as long-range beam-beam studies with wires at RHIC and the SPS.

Studies on energy deposition from collision debris in the magnets, in collaboration with INFN Milano and US-LARP, and incoherent electron cloud effects, together with GSI, were other key R&D items for HHH in 2007, as was the CERN-GSI collaboration on collective beam phenomena in high-intensity beams.

Deliverables: In the frame of WP1 (AMT) the final version of the web based database for SC Cables and Magnets was released to the public. The number of accesses to this database, mainly from outside CERN, much exceeds any expectation. Automatic tools which can import data from existing databases, e.g., for LHC, Tevatron, RHIC and possibly ITER, to the database core were also developed. Additional simulation tools were included in the accelerator physics code repository of WP3 (APD). A structured list of intensity limitations in the LHC injector chain was also completed in WP3 (APD).

Events:A total of 7 HHH workshops were organized in 2007, two in the frame of WP1 (AMT), one by WP2 (ABI), and four in the frame of WP3 (APD). The interest in HHH events was enormous and participation unexpectedly large. It included not only representatives from several European HHH partner laboratories, but also from Japan, and in particular a strong presence from the US-LARP, and a significant delegation from industrial companies. In addition, a CARE-HHH bilateral GSI-CERN meeting and a Memorial Symposium for Francesco Ruggiero were organized in the frame of WP3 (APD), integrated into one of the APD workshops.

Dissemination and outreach: The intensity of the dissemination effort of HHH information was maintained at a high level similar to 2006. Numerous invited talks were delivered, mostly by the HHH coordinators, which illustrated the HHH activity for various CERN and INFN committees, to the LHC experiments, at universities, as well as at workshops and conferences organized by other institutions. 22 new publications were issued from January through October 2007, most of which are already stored in the CARE database. The HHH web site was continually updated.

Exchanges and educational aspects: One Italian accelerator specialist was hosted by CERN for a total period of about one month with the support of HHH in the frame of WP1 (AMT) to work on energy deposition. The travel of three doctoral students active on HHH issues to BNL and/or FNAL was supported by HHH to participate in beam-beam experiments at RHIC and to collect information for the s.c. database, respectively. One junior scientist from GSI, Germany, was hosted and supported for HHH studies, in the frame of WP3 (APD). Three EU summer students and nine EU doctoral students were active at CERN on issues related to WP1 and 3 (AMT and APD), namely IR upgrade, web databases, beam-beam compensation, new injector synchrotrons, and crystal experiments. The first US-LARP Toohig fellow is being hosted at CERN for a period of one year. Two Russian scientists and two Italian fellows were also hosted at CERN to contribute to the estimation of the ion-crystal interaction. An Italian master student received a partial support for the completion of his master thesis on crystal collimation.

We acknowledge the support of the European Community-Research Infrastructure Activity under the FP6 “Structuring the European Research Area” programme (CARE, contract number RII3-CT-2003-506395).
