        abstract = {Superconducting YBa2Cu3O7-x (YBCO-123) is one of the
superconducting critical temperature as high as Tc {$\approx$} 93 K which can be
cooled with liquid nitrogen having a boiling point {$\approx$} 77K. This study aims
to observe the Meissner effect as a test of the material characteristics of
superconducting YBa2Cu3O7-x to show the nature of
superconductivityobserving the structure of the surface morphology and
element content using SEM-EDX technique, and conduct studies of
superconducting YBa2Cu3O7-x for the application of a magnetic field on
the cyclotron at the PSTA-BATAN Yogyakarta. superconducting material
when analyzed using SEM techniques have irregular morphology
microstructure with an average grain size {$\approx$} 3,575 {\ensuremath{\mu}}m. Based on EDX
analysis, the superconductor material YBa2Cu3O7-x contains the elements
C, O, CO, Y and Ba. Each has a percentage of 25,84\% by weight, 18,50
wt\%, 02,81\%, 10,57\% by weight, 31,60\% by weight. Based on the results
of the theoretical study of the cyclotron uses a magnetic field to a
superconductor material YBa2Cu3O7. These materials have the potential
that can be used to generate a magnetic field in a cyclotron accelerator
with the conditions of 5 mm diameter wire which has a critical temperature
(Tc) = 90 K, the critical current (Ic) = 22.221.593 A, the critical magnetic
field (Bc) = 8.88 T after cooling at 60 K are wound on an iron pole
diameter of 910 mm. The magnetic field superconducting cyclotron is
designed to operate current 1000 A to generate a magnetic field {\ensuremath{>}} 7 T so as
to produce a particle kinetic energy of 200 MeV.}
