A plasma beam dump uses the collective oscillations of plasma electrons to absorb the kinetic energy of a particle beam. In this paper, a modified passive plasma beam dump scheme is proposed using either a gradient or stepped plasma profile to maintain a higher decelerating gradient compared to a uniform plasma. The improvement is a result of the plasma wavelength change preventing the re-acceleration of low energy particles. Particle-in-cell simulation results show that both stepped and gradient plasma profiles can achieve improved energy loss compared to a uniform plasma for an electron bunch of parameters routinely achieved in laser wakefield acceleration.

BACKGROUND The community health service system was initially established in the rural areas of mainland China, but the utilization of community health service resources by the rural elderly population is not clear. OBJECTIVE In this study, evidence was combined to identify the factors that influence the use of health services, to reveal the gaps in community health services in rural China and the barriers that affect the usage of primary health services by the elderly population. METHODS Cross-sectional studies on the utilization of community health services by the rural elderly in mainland China published within the last ten years were retrieved from the China National Knowledge Infrastructure (CNKI), Wanfang, Medline and Web of Science (WOS) databases. The quality of the article was evaluated by the Critical Appraisal Skills Programmer (CASP), and obstacles to the utilization of community health services by the rural elderly population were analysed based on the Andersen model. RESULTS 24 studies were analysed, including 20 high-quality articles and 4 medium-quality articles. Three gaps were found: (i) The cognition of rural elderly residents does not match the current health security system. (ii) There is a gap between the supply of health service resources in rural communities and the health needs of elderly residents. (iii) The health services provided by rural primary health service institutions are not targeted. CONCLUSIONS The current situation of the utilization of community health services by the rural elderly population in mainland China is not optimistic. Several factors from the individual to the system level lead to low access and low utilization. This finding means that under the leadership of the government, it is necessary to integrate the strength of multiple departments to cooperate in improving the welfare system, policy publicity, health education, financial support, system guarantees and resource exchange and sharing for the elderly population in rural areas and to jointly promote community health services for the elderly population in rural areas.
