The Insertable B-Layer (IBL) is the new and innermost layer of the ATLAS Pixel detector. Shown in Figure 1 is the insertion in the detector in May 2014 and it is currently being commissioned. …

The Level-1 TDAQ for IBL is a VMEx64-based system consisting of 15 pairs of new Read-Out Driver (ROD) and Back-of-Crate cards (BOC) (14 for IBL staves, 1 for Diamond Beam …

The IBL VME crate in the counting room hosts 14 pairs of Back-Of-Crate (BOC) and Read-Out-Driver (ROD) cards, each pair servicing one stave. While the BOC mainly acts as an optical …

2015年2月19日 · The ATLAS Collaboration will upgrade its semiconductor pixel tracking detector with a new Insertable B-layer (IBL) between the existing pixel detector and the vacuum pipe of …

ATLAS is one of the four big LHC experiments and recently its Pixel Detector was upgraded with a new innermost 4th layer: the Insertable B-Layer (IBL) . The upgrade will result in better …

The Back-Of-Crate card (BOC) is driving the optical interface to the detector and distributing the LHC clock to all detector components. A brief overview of the firmware and test results from ...

2020年4月8日 · We are proposing a system that delivers the full IBL readout within 14 building blocks, fitting into a single 9U VME crate. Within this paper we described the basic functional …

To handle the data readout the currently used VME card pairs consisting of a back of crate card (BOC) and a read out driver (ROD) are being redesigned. This paper presents details of the …

2015年2月1日 · The main purposes of the BOC card are the distribution of the LHC clock to all Pixel Detector components as well as interfacing the detector and the higher level readout …

16 building blocks can be integrated into one readout crate and controlled by a Single Board Computer (SBC), using the VME bus. Data taking does not need the VME bus interface, other …
