  1. 1. Investigation of Ion Extraction Anomalies at TwinEBIS

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Niek van Woudenberg; [2023]
    Nyckelord :CERN; ISOLDE; Ion Source; EBIS; REXEBIS; TwinEBIS; Ion losses; Charge Breeding; Ion Extraction; CST Studio Suite; Physics and Astronomy;

    Sammanfattning : The electron beam ion source REXEBIS at CERN-ISOLDE delivers highly-charged ra- dioactive ions for post-acceleration in the HIE-ISOLDE LINAC. Research and develop- ment of components for electron beam ion sources is carried out at the TwinEBIS test stand, currently equipped with a Brillouin electron gun called MEDeGUN. LÄS MER

  3. 2. Automatic data processing of traction motor measured data and vibration analysis of test bench

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Arshey Dhangekar; [2021]
    Nyckelord :Electric motor; Traction motor; MATLAB; data processing; data analysis; COMSOL Multiphysics; FEM; test bench; natural frequency;

    Sammanfattning : One of the goals of ABB AB is to develop highly efficient electric motors for traction application. The demand for traction motors is increasing due to the rise in electric vehicles sale and railway locomotive engines. LÄS MER

  4. 3. Development and Implementation of a Mass Balancing System for CubeSat Attitude Hardware-in-the-Loop Simulations

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Guillermo Ledo López; [2019]
    Nyckelord :hil; hardware in the loop; simulation; satellite; simulator; platform; simulink; matlab; least squares; aocs; testing; attitude; dynamics; control;

    Sammanfattning : Spacecraft simulator platforms can simulate the microgravity environment of space on Earth, for the purposes of testing the Attitude and Orbit Control Subsystem of satellites. In order to do this, the satellite is mounted on a bench and the combined center of mass of this assembly is controlled by a series of moving masses. LÄS MER

  5. 4. Test bench for Nanosatellite Attitude Determination and Control System (ADCS)devices : Design and manufacture of a Merritt Cage

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Alvaro Cano Torres; [2019]
    Nyckelord :Helmholtz; Merri􀆩; Cage; Test; ADCS; Nanosatellite; Magne􀆟c; Orbit; Propaga􀆟on; Weightlessness; Air; Bearing.;

    Sammanfattning : Attitude Determination and Control System (ADCS) is often a complex system on-board any  satellite  which  needs  validation  and  testing  to  prove  its  operability  and  verify  its software  compatibility  with  hardware  and  other  subsystems.    One  failure  in  orbit  is extremely expensive in terms of cost and time due to payload preparation and launch.

  7. 5. Mullbänkar i Västergötland - funktion, innehåll, uppbyggnad och syfte.

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Ida Skog; [2018-05-07]
    Nyckelord :Helénstugan; Skövde; Mullbänk; Garden conservation; Earth bench;

    Sammanfattning : The mullbänk (a Swedish word for an earth bench, greenbank, bank of earth) is one of the garden's cultural heritage, but today often a forgotten part of the garden history. The mullbänk has historically worked, among other things, as a kind of insulation, a place for growing plants and a place to sit on. LÄS MER
