Themes variety from introductory lectures on algebraic cycles to extra complicated fabric during this number of lecture notes from the lawsuits of the Grenoble summer time university, 2001. The complex lectures are grouped less than 3 headings: Lawson (co)homology, explanations and motivic cohomology and Hodge theoretic invariants of cycles.

2. 3: Beam configuration in the RRC in the case of the AVF injection. 2: Accelerator parameters. 1 MHz Harmonics 5 5 5 Intensity 50 enA 50 enA 100 enA Beam Transport The beam extracted from the RRC is transported to the target in the E4 experimental area through the transport system shown in Fig. 4. The transport system consists of six dipoles (EBM1, EBM2, DAA1, DMA1, DAD4, DMD4), nine quadrupole triplets (QA01, QA02, QA11, QD12, QD13, QD14, QD15, QD16, Q4A1), a quadrupole septenary (TWISTER), a set of two dipoles (WD1, WD2) and a quadrupole doublet (WQ1, WQ2).
The unshaded one is the spectrum for all events without using the information from the active slit. 1-mm scintillator. The shaded one is the spectrum obtained by rejecting events having signals from the active slit. 1-mm scintillator are completely eliminated. The lower energy peak in the unshaded spectrum has a slightly larger width than the one at higher energy, due to the larger aperture of brass slit (3 mm) and the energy-loss straggling in the scintillator, but the difference is not significant because the resolution of HPGe has the largest contribution.
After correcting the position dependence, δtdiff = 212 and 218 ps (FWHM) have been obtained from the data of 3800-MeV 40 Ar and 2420-MeV 22 Ne, respectively. By assuming δtJ1 = δtJ2 , δtav is related to δtdiff as δtav = δt2J1 + δt2J2 δtdiff = , 2 2 33 which results in 106 and 109 ps (FWHM) for 40 Ar and 22 Ne, respectively. A silicon position sensitive detector (Si-PSD), Hamamatsu S2461, was used to measure the horizontal positions of the particles at F2. The Si-PSD is a strip detector consisting of 48 p-type silicon strips and an n-type silicon base with 250-µm thickness.
