“…The energy resolutions for electromagnetic and hadronic showers as determined in test beam measurements [35,36] are σ(E)/E ∝ 11%/ E/GeV ⊕ 1% and σ(E)/E ∝ 50%/ E/GeV ⊕ 2%, respectively. The energy and scattering angle of the scattered electron is measured in a scintillating fibre calorimeter SpaCal [37,38] with a resolution of σ(E)/E ∝ 7%/ E/GeV ⊕ 1%. The precision of the energy scale is 1% covering the polar angular range 154 • < θ e ′ < 174 • .…”

A measurement is presented of single-and double-differential dijet cross sections in diffractive deep-inelastic ep scattering at HERA using data collected by the H1 experiment corresponding to an integrated luminosity of 290 pb −1 . The investigated phase space is spanned by the photon virtuality in the range of 4 < Q 2 < 100 GeV 2 and by the fractional proton longitudinal momentum loss x IP < 0.03. The resulting cross sections are compared with next-to-leading order QCD predictions based on diffractive parton distribution functions and the value of the strong coupling constant is extracted.

“…The interaction vertex positions have an approximately Gaussian distribution in z with σ z ≈ 10 cm. The calorimetry system consists of the Liquid Argon calorimeter (LAr) covering the central and forward directions and the lead-scintillator spaghetti calorimeter (SpaCal) [52][53][54][55] measuring particles scattered backwards.…”

“…It consists of an electromagnetic section [53][54][55] with 1192 cells of size 4.05 × 4.05 × 25 cm 3 in front of a hadronic section with 136 cells of size 11.9 × 11.9 × 25 cm 3 . The total amount of passive material traversed by particles from the interaction vertex up to the SpaCal is of the order of one radiation length.…”

“…Two read-out channels represent a so-called submodule, eight of which are grouped into a supermodule. The energy resolution for the electromagnetic part is found to be σ E /E ≈ 7.5%/ E/GeV ⊕ 1% [52], for the hadronic section σ E /E ≈ 36%/ E/GeV ⊕ 4% [53].…”

The Fast Track Trigger (FTT) uses information from the central jet chambers of the H1 experiment to reconstruct track parameters. Its purpose is to contribute to the online selection of events on three levels within the H1 multi-stage trigger system. In this thesis a general analysis of the resolution of the track parameters obtained on the second trigger level is presented. These resolutions yield 4.11±0.01 mrad for φ, 118.7±0.2 mrad for θ and 3.968±0.002% for κ relative to the resolution achieved in the offline reconstruction. Furthermore the selection capability of the FTT with regard to events with D * mesons is investigated on all three trigger levels. These studies cover the kinematic regions of deep inelastic scattering (2 < Q 2 < 100GeV 2 ) and photoproduction (Q 2 ≈ 0).
