Ricardo Beltron / The second marker detection board was tested, there is a relevant attenuation from 3 GHz onward, and with the help of the PCB service we are trying to identify the source of the problem in order to produce a new board with better performances. The internal frequency generator of the board is under tests.
Measurements with the WR B-train in the POPS and RF feedback loops are now performed every week during MD day. The outcomes of the tests are summarised in the PS logbook
The manufacturing of the field direction calibration support are pending at the TE-MSC-MDT workshop.
The drawings of the LEIR B-train support are review and the orders are ongoing.
The design of the connection box, and the temperature regulation system for the LEIR B-train is ongoing. A prototype will be tested before the order of the final version.
Calibration model for B-train revised and optimised. Extrapolation of magnet’s transfer function at different ramp rates is being investigated.
Investigation on the % relative difference of using either 1 fluxmeter coil or 3 fluxmeter coils in series.
LEIR B-Train: A 600Hz ripple (50mVpp) is superimposed on the coil signal (400mVpp). Not seen by the integrator but it could be a problem for the offset drift.
SPS B-Train: Racks assembly in I8 by Maxime for the SPS B-Train is finished. We are waiting free space for the installation of our racks in the BA3 building. The 2 SPS-FEC have been ordered.
The optic fiber pulling, timing facility request, electrical network connection and computer network installation are pending.
Simulated B-Train: VHDL firmware test is ongoing. The new version of the Bresenham’s algorithm for the AD machine synthetic B-Train seems to work. We are able to plot one cycle vectors stored into different memory bunches.
Booster B-Train: The commissioning of the new B-train system is ongoing.
Issue with the front-end not yet fixed. 4 new racks have been ordered for the new building 245.
Simulated B-train
Added and tested Bresenham v2.0 : (B, t) vectors are now being
played in two different modes, either full or partial cycle mode.
Btrain, Simulated Btrain and White-rabbit
Just received from BE-CO the new Btrain-over-WR. Created a Btrain-Team/White-Rabbit-Btraingit repo to host this project as submodule and started working on the code to make the interface between WR and our user specific application.
Btrain FESA Acquisition
From FESA we are now able to acquire the B-field (measured and simulated). As well as the old Bup-Bdown.
FESA
Knowledge transfer from Martino (FESA)
The FESA class FSBT_BTG, which implements the simulated B-train, has been successfully tested on the lab test bench.
The FESA classes FSBT_INT and FSBT_MPD, which control the FMC integrator and the FMC peak detector cards respectively, have been successfully tested on the LEIR Btrain system.

Olaf Dunkel / Magnetic measurement interrupted for one week due to magnet power supply failure in SM18.
Meeting for new rotating shaft (diam. 40) held on 23-06-2017. Still some interfaces with cryostat insert to be clarified.

Ricardo Beltron / -HiLumi collars material:
A sheet of Sandvik stainless steel has been delivered to our section in the framework of the characterization of the material for the HiLumi collars. The sheet will be machined in order to obtain a cube sample, which will be measure in the dipole using the open-circuit method we are developing. The design of the sample and its holder is ongoing.
-Mu-metal for Crab Cavities test:
The magnetic characterization at 300 K and 77 K have been completed.

MQXFS5b:
The magnet is now in the Cluster D cryostat at 1.9 K.
Powering tests not yet started. The new configuration of the power converter (15 + 15 kA) requires some tuning.
First powering at limited current and first MM tests are expected next days.
We will take the occasion to train new operators (Xavier, someone else?).

PS / Regis Chritin / The bumper type 209 for pulsed measurements with corrugated chamber has been sent to 867 by Dominique Bodart. If the “test cage” is available next week (To be discussed with Jan Borburgh) measurements will be done that week.
RMC / Carlo Petrone / Further data analysis ongoing on data acquired on RMC, especially to correlate data mechanical sensors to magnetic measurements.
SPS / Regis Chritin / Quad SPS181 measured. I’ve compared our two fluxmeter for quadrupoles and the gap between their central coils is higher than 1.10-3. A calibration of these fluxmeters should be planned.
11-Tesla / Filippo Galli
Juan Garcia
Lucio Fiscarelli / Measurements conducted with J. G. Perez followed by data analysis. Some scripts for automatic data analysis and report generation have been written, tested, and improved with these files. Working on furtherimprovements.
Re-Mesuresdu bobine collarée 11T en B180 avec le système QIMM
MBH_C001:
The first collared coil assembly is being tested in bld.180 by using the upgraded QIMM system. The initial strange results were understood: the magnet was positioned as skew dipole and the rotation of harmonics was giving jumps around +/- 90 degrees. Measurements were repeated by introducing an angular offset on the probe and finally by rotating the magnet. New results are valid.
MM Internal Projects
Asset Management / Rocio Martinez
Eleni Tournaki / Application for generating assets codes and creating them automatically in inforEAM.
Studying the VacDM application developed by the vacuum team for managing assets and bar codes in inforEAM.
The barcode scanner was received, configured and tested for the two label sizes that were chosen for the inventorying process.
The order for the label printer was placed to the supplier on the 28/6 and is expected to be delivered in a week.
Some tables (MM employees, super classes & classes of MM equipment, etc.), which will be useful for the application which is being developed to ease the inventorying process are being prepared.
The Assets screen and the details of the equipment database are still being defined, but a first draft of the customisation for the Assets Screen in Infor EAM was sent to the CMMS support team to start implementing it.
