Golutvin celebrates 75th birthday at Dubna

Igor Golutvin, one of the leading scientists at JINR, Dubna, celebrates his 75th birthday in August. He is well known for several generations of large-scale experiments at JINR's synchrophasotron and at the accelerator of the Institute for High Energy Physics in Protvino, as well as at CERN.

Golutvin began to develop and study wire spark chambers for neutrino experiments during his first visit to CERN in 1964, at the time when online computers were first used. This experience helped him involve electronic methods in experiments at the synchrophasotron and at the U-70 accelerator at Protvino. Under his leadership, the USSR then had its first – and one of the world's first – apparatus to study elastic pp-scattering and K0K0regeneration.

In 1974 Golutvin was one of a group of physicists sent to CERN to establish a joint JINR–CERN experimental programme. The successful work by Golutvin and the Dubna team strengthened the participation of the JINR physicists at CERN and promoted the development of co-operation. As a result the first joint experiment, NA4, by the Bologna–CERN–Dubna–Munich–Saclay collaboration, was approved in 1975. Golutvin led the R&D and construction of large proportional chambers for this experiment.

At Dubna he organized a powerful base for R&D and mass-production of different types of wire detectors and their electronics. Drift and proportional chambers constructed under his leadership were used in experiments at Dubna and Protvino, and large-area chambers manufactured at Dubna were used in the SMC experiment at CERN and in HERA-B at DESY. In 1988 Golutvin initiated the Dubna silicon programme to develop applications of radiation-hard silicon detectors in experiments at colliders.

For the past 16 years Golutvin has been an organizer of international co-operation in the CMS project at the LHC. He has been spokesperson for the Russia and Dubna Member States (RDMS) collaboration in CMS since 1994. The RDMS–CMS collaboration, which involves 24 research institutes, was responsible for the design, construction and commissioning of the endcap hadron calorimeter and first forward muon stations, with active participation in the design and production of several other sub-detectors. Golutvin has also paid meticulous attention to development of the RDMS physics programme, grid-based computing and the CMS upgrade for the proposed Super-LHC.

• A session of the 13th Annual RDMS–CMS Collaboration Conference dedicated to Golutvin's 75th birthday will be held in Dubna on 10 August.


Leimen provides a charming welcome

The CHARM 2009 workshop, organized by GSI, took place on 20–22 May in the mediterranean ambience of Hotel Villa Toskana in Leimen. A total of 60 experts from four continents met at this international workshop on the physics of charm quarks to discuss the current state of research.

The main subjects apart from the production mechanisms of the medium-weight representatives of the quark family were hidden-charm and open-charm states and spectroscopy, as well as measurement of the properties of charmed baryons and mixing of neutral D mesons. Special attention was given to the discussion of experiments currently running, such as BESIII, which started last summer in Beijing, and to future experiments such as LHCb at CERN and the PANDA experiment proposed at the Facility for Antiproton and Ion Research, which will allow significant improvements in the precision of all kinds of measurements in this field, owing to the superior statistics. The next and fourth workshop in this series will most likely be held in autumn 2010 in Beijing.
