Present Status of the Rcnp Cyclotron Facility

چکیده
The Research Center for Nuclear Physics (RCNP) cyclotron cascade system has been operated to provide high quality beams for various experiments. In order to increase the physics research opportunities, the Azimuthally Varying Field (AVF) cyclotron facility was upgraded recently. A flat-topping system and an 18-GHz superconducting Electron Cyclotron Resonance (ECR) ion source were introduced to improve the beam’s quality and intensity. A new beam line was installed to diagnose the characteristics of the beam to be injected into the ring cyclotron and to bypass the ring cyclotron and directly transport low energy beams from the AVF cyclotron to experimental halls. A separator is equipped to provide RI beams produced by fusion reactions at low energy and by projectile fragmentations at high energy. Developments have been continued to increase secondary beams as white neutrons, ultra cold neutrons, muons and unstable nucleri.

متن کاملDevelopment of the Flat-top Acceleration System for the Rcnp Avf Cyclotron
A new flat-top acceleration system has been developed for an RCNP K140 AVF cyclotron to reduce the energy spread of a beam and to improve beam transmission to an RCNP K400 ring cyclotron. A flat-top cavity with a length of 700 mm and an outer diameter of 170 mm is capacitively coupled to a main resonator. A maximum peak harmonic voltage of 5 kV can be produced on a dee electrode by feeding powe...
متن کاملStudies of structure functions at a low - energy facility
We discuss the studies on structure functions at the possible future RCNP facility. At this stage, an electron-proton or proton-proton collider with √ s = 5 ∼ 10 GeV is considered. We explain large-x physics, nuclear modification of sea-quark and gluon distributions, and tensor spin structure function as the interesting topics at the facility. The large-x parton distributions are important for ...
متن کاملStudy of Extraction and Transport of Intense Highly Charged Ions for 18ghz Sc-ecris at Rcnp*
An 18 GHz superconducting ECRIS is installed to increase beam currents and to extend the variety of ions, especially for highly charged heavy ions which can be accelerated by RCNP cyclotrons. The production development of several ions like B, O, N, Ne, Ar, Ni, Kr and Xe has been already done and the further studies for those beam extraction and transport have been done in order to increase the ...
متن کاملIon Source Development at the Agor Facility∗
This paper discusses the present status of ion source development at KVI. Work is mainly focussed on increasing the beam intensity of the ECRIS injector and to optimize the beam transport and injection into the AGOR cyclotron. The ultimate goal is to deliver a 1 kW beam of heavy ions on target. Recent progress towards this goal is discussed. We also present the first results of beam extraction ...
