1：Experimental Design and Method Selection:

The study involved testbeam characterizations of irradiated CCPDv4 sensors using the FE-I4 beam telescope at the CERN SPS H8 beamline. The methodology included measuring hit efficiencies, time resolution, and cluster sizes under various irradiation fluences and bias conditions.

2：Sample Selection and Data Sources:

CCPDv4 sensors produced with the ams H18 HV-CMOS process were irradiated with reactor neutrons and 18 MeV protons to fluences between 1e14 and 5e15 neq/cm^

3：Samples were glued to ATLAS FE-I4 readout chips. List of Experimental Equipment and Materials:

Equipment included the FE-I4 beam telescope, a cooling box with a Huber Unistat chiller, Araldite 2011 epoxy glue, and a SET Accμra 100 flip-chip bonder. Materials included the irradiated sensors and readout chips.

4：Experimental Procedures and Operational Workflow:

Sensors were cooled to -25°C to reduce leakage current. Beam tests were conducted with high-energy pions, and data on hit efficiency, timing, and cluster sizes were collected using the telescope and readout systems.

5：Data Analysis Methods:

Data analysis involved calculating hit efficiencies from track matches, analyzing timing distributions with a clock-phase veto, and determining cluster size fractions using statistical methods.
