end, de-velop a test station to characterise the superconducting
material layer on the substrate and experimentally analyse the quality
of the super-conducting layer performance under a wide temperature range
from 300 K down to 4.2 K (e.g. measurement of RRR, critical temperature,
magnetic penetration depth). Based on the data, develop a model and
implement a numerical simulation to predict the influence of thermal
properties such as heat capacity, heat conduction and heat transfer
towards the substrate on the performance of the superconducting layer.
Analyse the results with ESR14 (USIEGEN) and ESR10 (INFN-LNL).

refinement and impurity doping aiming at Jc=1500 A/mm2 at 4.2 K and 16
T. Identify mechanisms in the conductor manufacturing and pre-material
properties to control the effects. To this end, design and produce wire
samples, measure transport and RRR and analyse the results. Assess
optimization potential by high-resolution scanning Hall probe microscopy
and magnetic force microscopy that will reveal the distribution of
magnetic flux to help quantifying the critical current density
homogeneity within the superconducting sub-elements of multifilamentary
wires. The objectives are attained in close collaboration with ESR1

supercritical, normal) in channels with hydraulic diameters from a few
mm down to micrometers in steady state and transient conditions. Perform
thermal measurements on actual insulated coils using the “stack” method
developed by CEA-SACM in cooperation with CERN. Implement the numerical

components for all parts of the cryogenic cooling system including
cryoplant and cryogen distribution to the devices (e.g. magnets,
radiofrequency cavities, current leads). In cooperation with ESR3,
establish an extensible efficien-cy model and develop a simulation tool
for different architectures and cooling schemes and determine the

thin films by measuring surface resistance of material samples at
different tem-peratures (2.5 K and 4 K) at three different, fixed RF

the sub-strate with at least two complementary methods. Consequently,
analyse the production recipes (ESR14 USIEGEN, ESR1 CERN) and
manu-facturing methods (ESR9 I-CUBE, ESR10 INFN-LNL) and examine impacts
on to the measured radiofrequency property results. Identify the coating
parameters impacting the RF performance most and establish a dependency

Develop a model for the impact of the method on the superconducting
perfor-mances of the final product, in particular in terms of
correlation with the microstructure (ESR12, TUW), RRR under cryogenic
conditions (ESR1, CERN) and compare to alternative forming methods
(ESR10, INFN-LNL). Due to the high strain operation lasting only for
millisec-onds, analyse the mechanical properties after the process in
the entire temperature range from 300 K to 4 K.

Define and set up a test bench to assess the effectiveness of the
manufacturing approach for radiofrequency performance at cryogenic
operation temperature of 1.8 K. Measure complete, 6 GHz cavities with
respect to their radiofrequency behaviour in cooperation with HZB
(ESR8). Understand the role of film purity and the absence of defects
versus the role of the thermal boundary resistance at the film/Cu
substrate interface in cooperation with CERN (ESR1) by modulating the
superconductor penetration into the Cu substrate and its influence on
the Q-slope. Derive correlations of radiofrequency performances of
thin-film cavities to the parameters of the sputtering process and the

refrigeration cycles
*Objectives:* Identify and describe a reference Neon-Helium (Nelium)
mixture refrigeration cycle for a target temperature range of 20-70 K,
indicating the Carnot efficiency for the refrigerator. Specify the
suitable refrigerants and their composition. Based on the cycle
speci-fications for different Nelium mixture ratios and overall magnet
cooling requirements obtained from CERN and CEA (ESR4), develop a
cooling system architecture and list suitable candidate components for
the different configura-tions in view of building the system in
co-operation with USTUTT (ESR15): turbo compressors, motors,
turbo-expanders, heat exchangers and circulators. In the frame of a
con-tract with an industrial supplier, specify and build a
turbo-compressor test setup in cooperation with ESR15 in the 10-30 kW
range with Nelium supply and gather data to understand limitations,
derive scaling laws, estimate suitable unit sizes of refrigeration power
and the associated required input power specifications. De-velop a cost

*Objectives:* Measure the impact of manufacturing processes and ionizing
radiation on the superconducting materials in wires (ESR2, ESR7, ESR13)
and thin films (ESR6, ESR14). For this purpose, prepare the brittle
samples using TEM lamella preparation by Focused Ion Beam as alternative
to the classical methods (grinding, polishing, ion beam thinning).
Characterise the microstructure by electron microscopy (SEM, TEM),
analyse diffusion characteristics from filaments to metal matrix and
investigate the chemical homogeneity across the filaments. For Tl-1223

coatings and MgB2 wires
*Objectives:* Understand in-depth the physics governing current
transport in Tl-based coatings with ESR6 (CNR-SPIN) and in MgB2 wires
with ESR7 (Columbus). Reveal correlations of superconducting properties
with material features. Assess local properties (grain boundary
transparency, presence of secondary phases and cracks, local texture)
using scanning probe studies. Optimise large-area, high-resolution
magnetic field mapping system to complement data from existing Scanning
Hall Probe Microscopy by increasing scan range and spatial resolution.
Perform transport measurements and SQUID magnetometry in high fields up
to 15 Tesla, with the KHM method to allow for sepa-ration of inter- and
intragranular currents. Examine micro- and nanostructure by SEM/TEM to

gases (Neon-Helium mixtures)
*Objectives:* Design a turbo compressor for the operation with light
gases (Neon/Helium mixtures) and perform aerodynamic and structural
analysis of the system. Study the thermodynamic cycles for large
cryogenic loads and their impacts on the working medium and the impact
on the machine induced by operation at low Mach numbers and the light
gas in cooperation with TUD (ESR11). Quantify static and dynamic
stresses, qualify different materials and propose design solutions that
are suitable for operation with light gases. Give guidelines for the
aerodynamic and mechanical design of the compressor and the
manufacturing techniques to be applied.
