The scaling of the two important figures of merit, the transformer ratio T and the longitudinal electric field E_{z}, with the peak drive-bunch current I_{p}, in a nonlinear plasma wakefield accelerator is presented for the first time. The longitudin

Multi-GeV trapped electron bunches in a plasma wakefield accelerator (PWFA) are observed with normalized transverse emittance divided by peak current, ϵ_{N,x}/I_{t}, below the level of 0.2 μm/kA. A theoretical model of the trapped electron emittanc

Plasma production via field ionization occurs when an incoming particle beam is sufficiently dense that the electric field associated with the beam ionizes a neutral vapor or gas. Experiments conducted at the Stanford Linear Accelerator Center explor

SummaryPlatelet thrombospondin (TSP1) forms a complex with high (HK) and low (LK) molecular weight kininogens. We isolated a proteolytic fragment from HK and LK heavy chains (12 kDa) recognized by TSP1 with a N-terminal sequence, K244ICVGCPRDIP254. L

SummaryMultifunctional proteins, e.g. high molecular weight kininogen (HK, 120 kDa) and the homotrimer, thrombospondin (TSP, 540 kDa), which have more than one domain on a single polypeptide chain, are particularly well-suited to be structural elemen

In recent experiments plasma electrons became trapped in a plasma wakefield accelerator (PWFA). The transverse size of these trapped electrons on a downstream diagnostic yields an upper limit measurement of transverse normalized emittance divided by

Recent experiments at SLAC have shown that high gradient acceleration of electrons is achievable in meter scale plasmas. Results from these experiments show that the wakefield is sensitive to parameters in the electron beam which drives it. In the ex
