| THHWPLCO04 | Open Hardware Experience on LNLS' Beam Diagnostics | ion, hardware, electronics, controls | 75 |
|
|||
| LNLS' diagnostics group has decided on adopting open hardware technologies for most of its projects, partnering with other institutes and companies to design and build its RF BPM electronics, from the analog front-end to the FPGA board. This decision resulted in advancements and learning, bringing new technologies, flexibility and knowledge, but also brought some hardships and new challenges. This talk details the history, advantages and difficulties of this open-hardware approach to beam diagnostics electronics. | |||

| THPOPRPO05 | Implementation of a Precision Logarithmic Ammeter | ion, experiment, operation, controls | 97 |
|
|||
| A precision and low cost ammeter is in development for the acquisition of sensor signals such as photodiodes, gold mesh (by photoelectron effect) and ionization chambers. One of the problems of conventional ammeters is the automatic scale selection, which hinders many measurements performed in ample energy range. The ammeter in development is based on a different methodology than present on most commercial systems, using a logarithmic amplifier. This choice of can provide a logarithmic response output in the range of pico to milliamperes. In addition, the system will have a trigger input for synchronism with external events and a Ethernet interface with EPICS driver. The electronic board is in development by LNLS, and is being installed and tested at the TGM Beamline. | |||

| THPOPRPO16 | Diagnostics at JINR LHEP Photogun Bench | ion, laser, emittance, cathode | 117 |
|
|||
| The photoinjector electron beam quality strongly depends on the laser driver beam quality. For laser beam diagnostics, a "virtual cathode" system was realized at the photogun bench located in the Veksler and Baldin Laboratory of High Energy Physics (LHEP) of the Joint Institute for Nuclear Research (JINR). The system allows one to image laser beam profile at the cathode. For imaging, the AVINE software suite developed in DESY Zeuthen is used. Equipment for emittance measurement using the slit method was installed. The original emittance calculation software EmCa was created and tested with laser beam. | |||
