Evidence of Dopant Type-Inversion and Other Radiation Damage Effects of the CDF Silicon Detectors

“…(2.37) 8 The annealing temperature is not accurately defined as even below this temperature some annealing occurs.…”

“…Each wedge consists of an electromagnetic component backed by a hadronic section. In the central electromagnetic calorimeter (CEM) [8], the scintillators are interleaved with lead layers. The total material has a depth of 18 radiation lengths (X 0 ) 4 .…”

“…Outside of the tracking systems and the solenoid, segmented calorimeters with projective tower geometry are used to reconstruct electromagnetic showers and hadronic jets [21][22][23] over the pseudorapidity range |η| < 3.6. The transverse energy is measured in each calorimeter tower where the polar angle (θ) is calculated using the measured z position of the event vertex and the tower location.…”

“…Electron candidates are identified in the central electromagnetic calorimeter (CEM) or in the forward, known as the plug, electromagnetic calorimeter (PEM) as isolated, mostly electromagnetic, clusters that match a reconstructed silicon track in the pseudorapidity range |η| < 1.1 and 1.1 < |η| < 2.0, respectively. The electron transverse energy is reconstructed from the electromagnetic cluster with a precision σ(E T )/E T ≈ 13.5%/ E T (GeV) ⊕ 2% for central electrons [21] and σ(E T )/E T = 16.0%/ E T (GeV) ⊕ 2% for plug electrons [24]. Jets are identified as a group of electromagnetic calorimeter energy (E EM ) and hadronic calorimeter energy (E HAD ) clusters populating a cone of radius ∆R ≈ (∆φ) 2 + (∆η) 2 ≤ 0.4 units around a high-E T seed cluster [25].…”

“…The CDF II calorimeter system covers a pseudorapidity region of |η| < 3.5 [36] and consists of electromagnetic and hadronic sections [40]. The physical towers are grouped into trigger towers that span 15 • in φ and approximately 0.2 in η for central towers (|η| < 1.0).…”
