An accelerator-driven subcritical system (ADS) program was launched in China 2011, which aims to design and build an ADS demonstration facility with the capability of more than 1000 MW thermal power multiple phases lasting about 20 years. The driver linac is defined be 1.5 GeV energy, 10 mA current cw operation mode. To meet extremely high reliability availability, designed much installed margin fault tolerance, including hot-spare injectors local compensation method for key element...
Distinguishing bipolar depression (BD) from unipolar (UD) based on symptoms only is challenging. Brain functional connectivity (FC), especially dynamic FC, has emerged as a promising approach to identify possible imaging markers for differentiating BD UD. However, most of such studies utilized conventional FC and group-level statistical comparisons, which may not be sensitive enough quantify subtle changes in the dynamics between In this paper, we present more effective individualized...
Although disturbances in biological rhythms are closely related to the onset of major depressive disorder (MDD), they not commonly assessed Chinese clinical practice. The Biological Rhythms Interview Assessment Neuropsychiatry (BRIAN) has been used evaluate MDD. We aimed assess and confirm reliability validity version BRIAN (C-BRIAN) patients with MDD.A total 120 MDD 40 age- sex-matched controls were recruited consecutively. Reliability was estimated using Cronbach's alpha, split-half...
A low energy beam transport (LEBT) system has been built for a compact pulsed hadron source (CPHS) at Tsinghua University in China. The LEBT, consisting of two solenoids and three short-drift sections, transports proton 60 mA 50 keV to the entrance radio frequency quadrupole (RFQ). Measurement shown normalized RMS emittance less than 0.2 π mm mrad end LEBT. Beam simulations were carried out compare with measurement are good agreement. Based on successful CPHS LEBT development, new China ADS...
Ion source development over the last 20 years at IMP is reviewed. For versatile purposes, several types of ion sources have been involved in research and work IMP, i.e., highly charged ECR (Electron Cyclotron Resonance) source, intense microwave or 2.45 GHz beam laser (LIS). In sources, SECRAL (Superconducting with Advanced design Lanzhou), Lanzhou all permanent magnet series made, which can cover operation frequency range 10-28 GHz. The LIS an Nd:YAG a maximum output energy 8 J ns pulse...
Experimental evidence of the property transverse coupling beam from Electron Cyclotron Resonance (ECR) ion source is presented. It especially interest for an ECR source, where cross section extracted not round along transport path due to magnetic confinement configuration. When ions are and accelerated through descending axial field at extraction region, horizontal vertical phase space strongly coupled. In this study, configuration between spaces achieved by back-tracking simulation based on...
LECR4 (Lanzhou electron cyclotron resonance ion source No. 4) has been successfully constructed at IMP and also connected with the Low Energy Beam Transport (LEBT) Radio Frequency Quadrupole (RFQ) systems. These magnet coils are cooled through evaporative cooling technology, which is first attempt an ECR in world. The maximum mirror field 2.5 T (with iron plug) effective plasma chamber volume 1.2 l. It was designed to be operated 18 GHz aimed produce intense multiple charge state heavy beams...
A new room temperature electron cyclotron resonance (ECR) ion source, DRAGON, is under construction at IMP. DRAGON designed to operate microwaves of frequencies 14.5–18 GHz. Its axial solenoid coils are cooled with evaporative medium provide an magnetic mirror field 2.5 T the injection and 1.4 extraction, respectively. In comparison other conventional ECR sources, has so far largest bore plasma chamber inner diameter 126 mm maximum radial fields 1.4–1.5 produced by a non-Halbach permanent...
Abstract Muon scattering imaging is a non-destructive method that utilizes cosmic ray muons to image materials with different atomic numbers. In recent decades, multiple international research institutions have developed various detection systems and reconstruction algorithms for applications in nuclear reactor core monitoring, material imaging, border security screening, non-proliferation. However, the methods assessing discrimination capability of corresponding system are not very...
The structure and preliminary commissioning results of a new 2.45 GHz ECR proton ion source dual-lens low energy beam transport (LEBT) system are presented in this paper. main magnetic field the is provided by set permanent magnets with two small electro-solenoid at injection extraction to fine tune for better microwave coupling. A 50 keV pulsed extracted three-electrode mechanism passes through LEBT length 1183 mm. This consists diagnosis chamber, Glaser lenses, steering magnets, final...
