The Achromatic Telescopic Squeezing (ATS) MD part II

This note describes the results obtained during the second so-called ATS MD where the record of Beta* was reached at IP1 and IP5 with a “pre-squeezed” Beta* of 1.2 m, while perfectly controlling the chromatic aberrations induced (non-linear chromaticity, off-momentum Beta-beating). Then, the ATLAS i...

Sumario:This note describes the results obtained during the second so-called ATS MD where the record of Beta* was reached at IP1 and IP5 with a “pre-squeezed” Beta* of 1.2 m, while perfectly controlling the chromatic aberrations induced (non-linear chromaticity, off-momentum Beta-beating). Then, the ATLAS insertion was squeezed further down to the target of the former LHC Upgrade Project (Phase I), that is to Beta* = 30 cm, using the Achromatic Telescopic Squeezing techniques. In view of this major achievement, the bar is fixed even higher for the next ATS MD’s, with an ultimate Beta* targeted to 10 cm for the two high-luminosity insertions ATLAS and CMS.
