Vadose Zone Remediation of CO2 Leakage from Geologic CO2 Storage Sites

Description: In the unlikely event that CO2 leakage from deep geologic CO2 sequestration sites reaches the vadose zone, remediation measures for removing the CO2 gas plume may have to be undertaken. Carbon dioxide leakage plumes are similar in many ways to volatile organic compound (VOC) vapor plumes, and the same remediation approaches are applicable. We present here numerical simulation results of passive and active remediation strategies for CO2 leakage plumes in the vadose zone. The starting time for th… more

A Multi Mega Watt Continuous Wave RF Window for Particle Accelerator Applications. Final Technical Report

Description: In this analysis the proposed 10MW window design is free of multipacting on the ceramic surface for the full power range, both in the traveling wave and full reflection mode. Near 7MW and 8MW in the traveling wave mode, multipacting might show up on the outer conductor of the matching section. These multipacting barriers are however very soft and are expected to be easily eliminated by regular RF processing. The multipacting analysis can identify early design problems while it is unable to prov… more

CHANDRA AND XMM-NEWTON OBSERVATIONS OF RDCS1252.9-2927, A MASSIVE CLUSTER AT z = 1.24

Description: We present deep Chandra and XMM-Newton observations of the galaxy cluster RDCS1252.9-2927, which was selected from the ROSAT Deep Cluster Survey (RDCS) and confirmed by extensive spectroscopy with the VLT at redshift z = 1.237. With the Chandra data, the X-ray emission from the intra-cluster medium is well resolved and traced out to 500 kpc, thus allowing a measurement of the physical properties of the gas with unprecedented accuracy at this redshift. We detect a clear 6.7 keV Iron K line in th… more
