  A new Radio-frequency quadrupole (RFQ), which operates at 800 MHz high
frequency and will enable to accelerate of the proton beam efficiently was
designed at KAHVELab (Kandilli Detector, Accelerator and Instrumentation
Laboratory) at Bo\u{g}azi\c{c}i University in \.Istanbul, Turkey. The so-called
PTAK-RFQ, which consists of two modules with a total length of less than one
meter will accelerate protons to 2 MeV at the Proton Testbeam at the Kandilli
campus, known as the PTAK project. The prototype of the first module of the 800
MHz PTAK-RFQ (called the PTAK-RFQ module 0), which captures and bunches the
proton beam injected from the ion source was fabricated by a local manufacturer
from ordinary copper material. The PTAK-RFQ module 0 was subjected to various
tests to ensure that its mechanics, pressure, field distribution, and frequency
are operationally adjusted. The facilitating solutions emerging from the
detailed testing of the PTAK-RFQ module 0 will ultimately guide all mechanical,
vacuum, rf testing, final design, and manufacturing processes of the final
PTAK-RFQ. The PTAK-RFQ module 0 was first subjected to vacuum tests and then to
detailed vacuum leak tests. Subsequently, low-power rf measurements were
performed for tuning of field and frequency. The tuning algorithm developed by
CERN was optimized for 16 tuners and 6 test field points to be adjusted to the
PTAK-RFQ module 0 to the desired field distribution. The tuning algorithm is
based on a response matrix, whose inputs are created by bead-pull measurements
of individual tuner movements. The tuning algorithm gives some predictions for
corrective tuner movements to achieve desired field distribution. In the
framework of all these RF tuning processes, the field distribution was tuned
through the tuning algorithm and then the frequency was tuned manually.
